Nowadays we need to dive into how one can higher use and perceive the knowledge from the preferred website online pace take a look at instrument Pingdom. You’ll use it to do what we name a waterfall research of your WordPress website online. This assist you to temporarily diagnose efficiency problems, and in addition no longer misdiagnose an issue.

Numerous occasions we see WordPress customers decoding the knowledge improper within the Pingdom pace take a look at instrument, and this ends up in every so often configuring a website online to a state even worse than prior to. Remember the fact that all equipment like this are for use as guides, they’re by no means 100% correct. The essential factor is to be constant and use the similar instrument during your entire exams.


Pingdom is an organization primarily based out of Sweden (now owned through SolarWinds) that provides plenty of other services and products, corresponding to uptime tracking, web page pace tracking, transaction tracking, server tracking, and customer insights (RUM). Most probably some of the issues they’re maximum widely known for is their loose website online pace take a look at instrument. It is likely one of the most well liked performance testing tools within the WordPress group.

Nonetheless on the lookout for that highest WordPress host?

  • South The usa – Brazil – São Paulo

Be aware: We’ve spotted that sometimes no longer the entire take a look at places can be to be had. That is in all probability as it has long gone down for repairs or it were given overloaded with too many of us looking to run exams on it. If a take a look at web site location that you just’ve been the usage of is now not there, take a look at again in an hour or two. Possibly it’ll reappear.

The trying out location you select is in truth essential because it pertains to the bodily location of the place your website online is in truth hosted. That is the place a little bit factor known as network latency comes into play. However we’ll get into this in additional element beneath.

Waterfall Research with the Pingdom Velocity Take a look at Software

A internet web page is made up of various belongings, corresponding to HTML, JavaScript, CSS, photographs, and movies. Every of those generates requests to render what you spot in your website online. Generally the extra requests you could have, the slower your website online will load. That isn’t all the time the case, however it’s true more often than not.

Beneath we’re going to get a divorce every Pingdom segment and provide an explanation for in additional element what the tips method because it relates to the whole efficiency of your website online and how one can do a waterfall research.

Pingdom Abstract

As you’ll see we ran our first test and we scored an 88/100 on Pingdom and the overall load time is 541 ms. It we could us know the overall measurement of our blended belongings and the choice of requests.

Pingdom speed test before DNS and cache

Pingdom pace take a look at prior to DNS and cache

We then ran an additional test and now our general load time is 392 ms with the similar web page measurement and choice of requests! What’s that every one about? ? Chances are you’ll realize this if you’re operating your website online during the Pingdom pace take a look at instrument more than one occasions. Greater websites will realize even higher variations.

There are 3 major the explanation why occurs: DNS caching, CDN caching, and WordPress caching. Because of this you will have to all the time run exams more than one occasions. After all, exterior calls to third-party assets and APIs may additionally affect this. To find out why additional beneath in our waterfall analysis.

Pingdom speed test after DNS

You’ll’t put out of your mind the person revel in! However relaxation confident, we can be sharing with you some guidelines and tips additional beneath on how we were given the above web site to the place it’s, so stay studying.

Pingdom Efficiency Insights

The efficiency insights segment of the Pingdom pace take a look at instrument used to be got rid of in 2018 and is now not to be had. That is in all probability as a result of one of the tips they had been reporting are now not as related as they was. On the subject of internet efficiency optimizations, issues are all the time converting. Additionally, this segment most likely brought about extra hurt than just right with other people looking to chase after the easiest Pingdom ranking.

Pingdom efficiency insights

Alternatively, we’re leaving this segment in our submit as it’s essential to know how those rankings are calculated. Those are necessarily all in keeping with the Google PageSpeed Insight rules. Typically, in case you support those in your web site, you will have to see a lower on your total load occasions.

Listed here are some of the classes that the efficiency insights segment was made up of:

  • Keep away from Dangerous Requests
  • Decrease Redirects
  • Leverage Browser Caching
  • Decrease Redirects
  • Take away Question Strings From Static Assets
  • Serve Static Content material From a Cookieless Area
  • Parallelize Downloads Throughout Hostnames
  • Specify a Cache Validator
  • Specify a Range: Settle for-Encoding header

Now let’s dive into a few of these and spot which of them are nonetheless related lately.

Keep away from Dangerous Requests

Fending off dangerous requests is all the time related! This caution is simply love it sounds, it’s a request that might no longer be finished effectively. This usually occurs you manually hyperlink to an asset or symbol which has since been deleted, leading to a 404 error. This displays up as an orange circle in Pingdom, at the side of a 404 at the reaction header standing.

Avoid bad requests - 404 error

Keep away from dangerous requests – 404 error

At all times be sure each request in your web site returns with luck standing. This may increasingly be certain that there aren’t any queries being generated to belongings which now not exist.

Decrease Redirects

Too many redirects are all the time one thing you wish to have to be careful for. Easy redirects like a unmarried 301 redirect, HTTP to HTTPS, or www to non-www (vice versa) are superb. And a large number of occasions those are wanted in positive spaces of your website online. Alternatively, every has a value on your web site’s efficiency. And in case you get started stacking redirects on best of one another, it’s essential to comprehend how they affect your web site’s efficiency. This is applicable to web page and submit redirects, symbol redirects, the entirety.

Decrease redirects in PingdomHow a lot do redirects affect your web site? Let’s do some take a look at. First, we run a speed test on our touch us web page: As you’ll see beneath we get a complete load time of 417 ms.

Website speed test with no redirects

Site pace take a look at with out a redirects

We then regulate the URL fairly and run some other speed test to look the affect of more than one redirects. As you’ll see, the similar web page now takes 695 ms to load. That’s an build up of 66%. Yikes!

Take a look at our in-depth submit on WordPress redirects, and the most efficient practices for quicker efficiency.

Leverage Browser Caching

A quite common caution other people fight with is leverage browser caching. To position it in laymen’s phrases, each script in your WordPress web site must have an HTTP cache header hooked up to it (or it will have to). This determines when the cache at the report expires. To mend this, be certain that your WordPress host has the right kind cache-control headers and expires headers setup. Kinsta has those headers in position on all of our servers. Take a look at the stairs on how to add caching headers to your server manually.

Leverage browser caching - caching headers

Leverage browser caching – caching headers

The opposite factor is that while you’re loading third-party scripts you don’t have get right of entry to so as to add the caching headers, as you don’t have any management in their internet servers. Commonplace culprits come with the Google Analytics script and advertising and marketing pixels, like Fb and Twitter. To mend this you’ll host your Google Analytics script in the neighborhood (despite the fact that this isn’t formally supported) with a plugin like Perfmatters. WP Rocket additionally now has an strategy to host your Fb advertising and marketing pixel in the neighborhood.

Transferring scripts in the neighborhood can range in the case of how a lot it affects your web site’s efficiency. The only merit is that then you have entire management over the report and will serve it from your individual CDN. This additionally gets rid of some other third-party DNS request. Alternatively, it’s additionally essential to needless to say those recordsdata may already be cached in other people’s browsers.

See our in-depth submit on how one can fix the leverage browser caching warning.

Take away Question Strings From Static Assets

Any other not unusual factor is coping with question strings. Your CSS and JavaScript recordsdata most often have the report model at the finish in their URLs, corresponding to Some servers and proxy servers are not able to cache question strings. So through disposing of them, you’ll every so often support your caching.

There are WordPress plugins like Remove Query Strings From Static Resources or Perfmatters which will do that for you mechanically. Or you’ll do it manually with code.

Alternatively, prior to you right away cross strips out question strings in your web site it’s essential to grasp why question strings are used. Versioning on recordsdata is usually utilized by WordPress builders to get round caching issues.

As an example, in the event that they push out an replace and alter taste.css from ?ver=4.6 to ?ver=4.7, it’ll be handled as a fully new URL and gained’t be cached. When you take away the question strings and replace a plugin, this might outcome within the cached model to proceed serving. In some circumstances, this might spoil the illusion of your web site till the cached useful resource expires or the cache is totally flushed.

Additionally, some CDNs can cache question strings. The Kinsta CDN can and does through default. So in case you’re a Kinsta consumer, question strings are already cached in your belongings.

Serve Static Content material From a Cookieless Area

We’ve an in-depth submit on how one can maintain the serve static content from a cookieless domain caution. Numerous occasions you’ll forget about this caution as new protocols corresponding to HTTP/2 now make this much less essential. The price of a brand new connection is most often dearer than streaming the entirety over the similar connection. Alternatively, two tactics to unravel that is to make use of a CDN supplier that strips out the cookies or create a separate area and or subdomain.

Parallelize Downloads Throughout Hostnames

The “Parallelize Downloads Throughout Hostnames” caution effects on account of a limitation of HTTP/1.1 and internet browsers being restricted to the choice of concurrent connections they are able to make to a number; which is usually 6 connections. This caution is usually noticed on web pages with numerous requests. Up to now, the one method to get round this limitation is to put into effect what they name area sharding. Alternatively, if you’re the usage of a internet host or CDN provider that supports HTTP/2, you’ll safely forget about this now as more than one assets can now be loaded in parallel over a unmarried connection. However you’ll additionally take a look at our educational on how to fix the parallelize downloads across hostnames warning through imposing area sharding.

Specify a Cache Validator

This caution refers to lacking HTTP caching headers which will have to be incorporated on each foundation server reaction, as they each validate and set the duration of the cache. If the headers aren’t discovered, it’ll generate a brand new request for the useful resource each time, which will increase the burden in your server. Those headers come with last-modified, ETag, Cache-Keep an eye on, and Expires. Identical to with the leverage browser caching caution, those headers will have to mechanically be added through your WordPress host. In case you have third-party requests you’re seeing this on, there may be not anything you’ll do as you don’t have management over their internet servers.

Specify a Range: Settle for-Encoding Header

We’ve an in-depth submit on how one can repair the Specify a Vary: Accept-Encoding header caution. That is an HTTP header and will have to be incorporated on each foundation server reaction, because it tells the browser whether or not or no longer the customer can care for compressed variations of the content material. That is mechanically added on all Kinsta’s servers

Pingdom Reaction Codes

The following segment in Pingdom pace take a look at instrument is the reaction codes. Reaction codes, additionally known as HTTP status codes are like a brief word from the internet server that will get tacked onto the highest of a internet web page. It’s a message from the internet server letting you understand how issues went when the request to view the web page used to be gained. Some not unusual ones are:

  • 200: “The whole lot is OK.” That is the code this is delivered when a internet web page or useful resource acts precisely how it’s anticipated to.

    Example of Pingdom 200 response code

    Instance of Pingdom 200 reaction code

  • 301: “The asked useful resource has been moved completely.” This code is delivered when a internet web page or useful resource has been completely changed with a special useful resource. It’s used for permanent URL redirection.

    Example of Pingdom 301 response code

    Instance of Pingdom 301 reaction code

  • 404: “The asked useful resource used to be no longer discovered.” The commonest error message of all of them. This code implies that the asked useful resource does no longer exist and that the server does no longer know if it ever existed.

    Example of Pingdom 404 response code

You’ll learn extra about the entire other reaction codes in our in-depth submit on HTTP status codes.

Content material Measurement and Requests through Content material Kind

The following sections are the content material measurement through content material sort and the requests through content material sort. Every of those turns out to be useful to temporarily see what’s taking over probably the most assets in your internet web page. In keeping with HTTP Archive, photographs normally make up for 43% of a median internet web page’s general measurement. We additionally see this to most often be the case as smartly. Alternatively, as you’ll see beneath in this web site, it’s not all the time the case.

Pingdom content type

Pingdom content material sort

For optimizing your photographs, we extremely counsel studying our in-depth submit on how to optimize images for web. There are lots of nice equipment and plugins in the market to additional compress your photographs and make sure they aren’t the majority of your website online’s web page load. And in our case above, the web site is benefiting from the usage of massive font superior icons rather than photographs. This will also be one nice technique that makes an enormous distinction. And naturally, we have now some further guidelines in our page speed guide on how one can additional lower your content material measurement.

Content material Measurement and Requests through Area

The content material measurement and requests through area segment is an effective way to temporarily see which exterior services and products and scripts in your website online. In our instance, you’ll see that we have got all of our belongings loading from our CDN. Then there may be the preliminary HTML DOC load for the website online from the internet server, and an exterior name to the Google Analytics area. Relying upon your web site you may have much more exterior services and products, corresponding to Fb, Twitter, Hotjar, SumoMe, AdRoll, New Relic, CrazyEgg, and many others.

Pingdom requests by domain

Pingdom requests through area

Typically the less exterior requests you’ll make the easier, as a result of every exterior services and products introduces its personal latency, TLS handshake delays, DNS lookups, and many others. Be sure to learn our in-depth submit on how one can identify and analyze external services in your WordPress web site.

Typically, it’s easiest to scale back the choice of requests up to conceivable and host the belongings in a single position, corresponding to transferring them in your internet server or CDN. One instance can be font superior. As a substitute of linking to the exterior script for font superior, obtain it, and serve it up without delay.

Pingdom Waterfall Chart

And final however no longer least, we have now the Pingdom pace take a look at instrument requests segment which generates a waterfall chart of the entire person requests in your internet web page (as proven beneath). You’ll then analyze every request to look what’s inflicting delays and function problems in your web site. That is what we imply once we say we’re doing a waterfall research. Beneath is a extra in-depth abstract and or definition of what every standing colour method.

DNS (Crimson)

So what’s DNS? Neatly, call to mind it like a telephone ebook. There are servers known as Area Title Servers which grasp the details about your website online and which IP it will have to be routed to. While you first run your website online via Pingdom, it plays a contemporary search for, and it has to question the DNS data to get the IP knowledge. This ends up in some further search for time. The positioning of the DNS server additionally issues.

DSN delays in Pingdom

DSN delays in Pingdom

While you run your website online via Pingdom greater than as soon as, it caches the DNS as it already is aware of the IP knowledge and doesn’t have to accomplish the search for once more. That is one explanation why your website online seems quicker after operating it via Pingdom more than one occasions.

As you’ll see within the display beneath, at the second take a look at we ran, the DNS lookup time at the preliminary DOC load is on 3.6 ms. Generally it’ll drop to 0 ms, in reality, it will have to, because the request is already cached. That is one space a large number of other people misread!

Cached DNS in Pingdom

Cached DNS in Pingdom

Additionally, you’ll additional optimize it through the usage of a premium DNS provider, plus it comes with a large number of additional advantages. Our Cloudflare’s loose DNS may be rapid!

There also are different the explanation why your website online may seem quicker after more than one exams. A type of is if you’re the usage of a content delivery network (CDN). For the ones of you no longer acquainted with a CDN, this is a community of world servers which cache your content material (JS, CSS, Photographs, and many others.) in places nearer to the customer. While you first run your website online via Pingdom, it would must snatch the belongings from the CDN contemporary. A CDN cache works similar to DNS, as soon as it’s cached, it’s then a lot quicker on consecutive so much.

Any other tip on dashing up DNS is to make use of DNS prefetching. This permits the browser to accomplish DNS lookups on a web page within the background. You’ll achieve this through including some strains of code to the header of your WordPress web site. See some examples beneath.


Or if you’re operating WordPress model 4.6 or more recent, it’s possible you’ll need to use resource hints. Builders can use the wp_resource_hints filter out so as to add customized domain names and URLs for dns-prefetchpreconnectprefetch or prerender.

SSL (Pink)

The pink standing colour stands for the time that your browser takes to do an SSL/TLS handshake. Each time you run a website online over HTTPS it method there may be an SSL certificates concerned and time beyond regulation concerned because of the encryption procedure (SSL/TLS handshake). On our instance area, we have now a certificates on each our internet server at Kinsta and our CDN, KeyCDN. So there may be an SSL negotiation time on each the preliminary HTML document load from the internet server and our belongings.

SSL load time in Pingdom

SSL load time in Pingdom

Whilst there may be slight overhead to operating HTTPS, it very negligible now because of HTTP/2, which is a brand new protocol serving to accelerate the internet! Because of browser give a boost to HTTPS is needed to make use of HTTP/2. Take a look at our ultimate guide to HTTP/2.

It’s additionally essential to notice that even in 2018 no longer all suppliers but give a boost to HTTP/2. This contains each from the internet internet hosting aspect and the CDN aspect. So when you find yourself buying groceries round for internet hosting and CDNs, be sure each give a boost to it! Kinsta is proud to give a boost to HTTP/2 for all of its WordPress shoppers.

As of mid-2018, Pingdom in any case upgraded their instrument to make use of Chrome 60 and better. You’ll see the user-agent getting used within the request header. In the past they had been the usage of Chrome 39, and Chrome didn’t support HTTP/2 until version 49. So we’re happy to mention that the Pingdom instrument now displays the entire benefits of HTTP/2 when operating exams! ?

Attach (Teal)

The attach time in Pingdom is relating to the TCP connection, or the overall time required to create a TCP connection. You don’t actually want to know how this works, however that is merely a verbal exchange approach between the host/consumer and the server that has to happen.

Pingdom connect time

Pingdom attach time

Wait (Yellow)

The wait time in Pingdom is in truth relating to the time to first byte, often referred to as the TTFB in some equipment. TTFB is a size used as a sign of the responsiveness of a internet server or different community useful resource. Typically, anything else beneath 100 ms is appropriate and just right TTFB. In case you are drawing near the 300-400 ms vary you may have one thing misconfigured in your server or it may well be time to improve to a greater internet stack.

Wait time - TTFB

Wait time – TTFB

One of the simplest ways to decrease your TTFB? The most efficient two tactics are efficient WordPress caching and a CDN. So let’s run a pair exams.

TTFB With out WordPress Host Cache

We first ran a test after clearing the cache on our WordPress web site. This implies it has to preload the cache once more. As you’ll see our general load time used to be 541 ms and the TTFB (wait time) on our preliminary request used to be 185.2 ms.

Pingdom TTFB before WordPress cache

Pingdom TTFB with out WordPress cache

TTFB with WordPress Host Cache

We then ran the test again. It’s now serving without delay from cache. As you’ll see our general load occasions dropped all the way down to 392 ms and the TTFB at the preliminary request is now 52.8 ms! That’s the distinction caching makes.

Pingdom TTFB with WordPress cache

Pingdom TTFB with WordPress cache

In case you have a website online this is serving guests in several portions of the rustic, or all over the world, the opposite simple method to enormously lower your TTFB is to make use of a CDN. We once more ran a couple of exams to turn the variation.

TTFB with out CDN

We first ran a test with our CDN disabled and as you’ll see our general load time used to be 1.93 s and our reasonable TTFB on an asset used to be round 176 ms.

TTFB without CDN

TTFB with out CDN


We then enabled our CDN and ran the test again. As you’ll see our general load occasions dropped down to one.21 ms and our reasonable TTFB on a CDN asset is now 4.6 ms! What a distinction a CDN could make.



Any other essential factor to notice is that we selected the “Pacific – Australia – Sydney” location to accomplish this take a look at. Why? As a result of we would have liked to turn you the actual development that may be had. Our WordPress web site on this instance is hosted through Kinsta at the Google Cloud and situated in a central location in america. Via appearing the take a look at in opposition to Australia we’re ready to turn how the Kinsta CDN caching will increase the velocity and decreases the TTFB.

And naturally, having a just right WordPress host with a moderately idea out structure may be the most important to reducing your TTFB.

Ship (Orange) and Obtain (Inexperienced)

The ship and obtain standing’s in Pingdom don’t actually want a lot of a proof. The ship time is just the time it takes for the internet browser to ship records to the server. And the obtain time is the time it takes for the internet browser to obtain records from the server. Either one of those will most often be very low or non-existent on your exams.

HTTP Reaction Headers

You’ll additionally click on on a person request whilst doing all your waterfall research and spot the HTTP reaction headers. This gives precious knowledge. Within the display beneath we will be able to immediately see issues corresponding to gzip is enabled on the web server, and that it’s being served from cache (HIT, would show MISS otherwise), the cache-control headers, expires headers, the browser user-agent and extra.

Case Find out about Area Configuration

If you were given this some distance down in our waterfall research submit then you’re in for a deal with. It’s all the time demanding to look other people percentage guidelines and case research however then no longer percentage how they were given there. So beneath is our actual configuration for the case learn about area used above! Be happy to copy it.


  • The case learn about area ( is hosted with Kinsta at the Google Cloud Platform in america (Council Bluffs, Iowa, USA (us-central1).
