10 Sites to Test Your Blog’s Performance (Page Speed, Caching, Server)

[This post is part of the Ultimate Guide to Launching a WordPress-Powered Blog series.]

You may have experienced a lot of changes and updates to your blog throughout this entire series and at some point (or many points) you may have wondered what the actual benefit of all of these things might actually be.

Well, there are definitely some easy ways to find out! In fact, you’ll want to not only bookmark these but also use a number of them to get different perspectives.

In fact, it’s a good practice to do some tests after you do anything significant to your blog, especially as it relates to your WordPress Theme, any WordPress Plugins, any 3rd party scripts, any hosting/server/dns changes, and more!

Here are 10+ sites and web services/apps that can help you test your blog’s speed, the new caching systems you have in place, and any other optimization and/or changes that you’ve made to your blog.

1. Firebug + Yahoo! YSlow

Love me some Firebug and Yahoo! YSlow plugin. Definitely check those out!

2. Firebug + Google Page Speed

Make sure to get the Google Page Speed add-on too!

3. Firebug + Hammerhead

Hammerhead is a simple add-on that shows the load time of a website. Easy.

4. Pingdom Tools

Pingdom’s Toolset is amazing. I use this all the time.

5. Load Impact

This one is a personal favorite as it provides a stress-test to see if your new server or hosting provider can handle a huge surge of traffic. Check it out here. As you can see by my graph above a “flat line” means your server is amazing and the load tests aren’t even close to overloading the system.

6. Web Page Test

I standard test that’s comprehensive and yummy. Check it out here.

7. Gomez Instant Test Pro

This service is free although you have to fill out a bunch of information. You can quickly insert some “bogus” info and get the test done.

8. Redbot

Redbot is simple and easy to use. You’ll need a bit more native understanding to execute on some of their suggestions though.

9. Cache Test

This manual test is one way to not only “test” your system but learn more about caching in general.

10. Compression Check

See if you’ve got compression turned on to speed up your site!

11. Compression GZIP Check

Another simple test to check compression and GZIP.

Hope those help and can provide you with enough firepower to test out your sites and blog! Let me know if I’m missing one that you use!

    Hey John, I’ve done some of these already. But I’m thrilled that there are more and I now have a one-stop-shop listing of them all. Bravo, my brother!

    • http://john.do John Saddington

      sure thing joe!

  • http://krogsgard.com Brian Krogsgard

    Loads.in is kind of fun.

    • http://john.do John Saddington

      great site too!

    • http://www.geekforhim.com Matthew Snider

      I find this to be way off in terms of speed compared to other tools.

      • http://john.do John Saddington

        i’ve found it mixed as well. i’ve found some sites that do really well and then some sites (like mine) where the results are mixed.

        • http://www.geekforhim.com Matthew Snider

          Okay at least I am not crazy!

  • http://www.maztek.com Tracy Mazelin

    Hey John,

    Just wanted to say thanks for all your excellent posts. I recently launched my own blog using the standard theme and followed through many of the tutorials found in this site. I then did another for a client of mine and today I’m on my third installation of the theme for a pastor. The tutorials have sure saved me a LOT of time. Thanks for the value your adding to the blogging community.

      thanks so much tracy! glad you could get it all running! (and a client…!)

  • Joseph

    I’ll be using a few of these. Didn’t know anything like this existed. Thanks for sharing them with us. I’m learning so much here at tentlbogger.com :)

    • http://john.do John Saddington

      tent “l” bogger! ;)

  • http://dustinstout.com Dustin W. Stout

    Awesome stuff John! I don’t know if I understand ALL of it, but I can definitely utilize most of these tools! Thanks again!

    • http://john.do John Saddington

      at some point you will… you’re growing in your blogging skills…1

  • http://www.jesushatespapyrus.org michael buckingham

    Ok…so my blog comes up as not compressed.

    So what’s the next step?

    • http://john.do John Saddington

      you using any caching systems?

      • http://www.jesushatespapyrus.org michael buckingham

        Yeah. wp-cache

        • http://john.do John Saddington

          have you tried wp-super-cache? whats’ your hosting? if you can (and want) w3 total cache does compression.

  • http://www.justcris.com Cris Ferreira

    John, that’s exactly what I needed. I didn’t know these sites you mentioned, so I’ll have to check all of them. It’ll be a busy weekend for me ;-)
    Thanks very much!

    • http://john.do John Saddington

      sure thing cris!

  • http://getbusylivingblog.com Benny

    One that’s kinda fun is http://whichloadsfaster.com/

    I tested your against that “other” problogging site and guessed which loaded faster? :)

    • http://john.do John Saddington

      teehee!

    • http://john.do John Saddington

      i got this… http://cl.ly/6Jxd

  • Brandon

    My site loaded in 7.4 seconds…is that ok?

    • http://john.do John Saddington

      wordpress.com is fast but you lose a lot of benefits of going self-hosted.

  • Brandon

    This might be depressing for you, but I don’t have anything set up on my site…and it loads pretty fast.

    Look at this: http://whichloadsfaster.com/?l=www.bigb94.wordpress.com&r=www.tentblogger.com

    You have a lot of caching and performance plugins on your site, and I have nothing. Is it because I use wordpress.com that makes it fast?

    • http://john.do John Saddington

      what do you mean?

      http://cl.ly/6LIe

      • Brandon

        In my face! haha… I guess it was that site. But when you switch to self-hosted, do you really lose that much speed?

        • http://john.do John Saddington

          you can if you choose a terrible hosting provider.

  • Prajeeth

    Thanks John for the post.
    I tested our church website and 65% faster.
    I would be exploring more on these websites and check the speed of our website.
    Cheers – PJ :)

  • Chad

    Just tested three of my sites using the google’s page tester. What is a good score? I tested your site and I got a score of 80/100, while one of my sites got a score of 74/100 and the other two sites got scores of 72/100.

    • http://www.geekforhim.com Matthew Snider

      I am sitting at a 92 right now. I would say 85 and above is what you should aim for. Proper caching and server setup and 90 is pretty easy. AT that point its all optimization.

      • http://john.do John Saddington

        i agree with matthew here. even this site could be optimized more! some of the tests are “off” though because they require that you change some of the test settings to pull in correct data… but i’m not crazy when it comes to the point system.

        it’s quite obvious when blogs are killing it in terms of speed and some of the “top” blogs out there have terrible ratings in these tests… but who cares!

        ;)

    • http://john.do John Saddington

      try to focus on each section of the report and see if you can optimize individually.

  • Kevin

    Thank you so much for making this site! It has really opened my eyes to everything that needs to go into making a good blog. Cheers!

    • http://john.do John Saddington

      sure thing kevin!

  • http://www.pagelabs.com Tyler Brinks

    Thanks for putting together a comprehensive list of tools. The all do well to help the web become a better place if we’d all only take the advice they provide.

    Now, I’m a bit biased, but I’d like to throw PageLabs in the ring. PageLabs does what some of these sites do in terms of performance, but our tool can measure an entire website as well as content spanning pages like scripts and images. We also have a proxy service that speeds sites up 3 to 4x in most cases using aggressive caching and distributing content via our global CDN.

    Take a look at http://www.pagelabs.com – give our free speed test a try.

    I know it’s a plug, but we’re trying to help make the web a better place one site at a time.

    • http://john.do John Saddington

      thanks tyler.

  • http://.loadzen.com Martin

    This is a comprehensive list, can I also suggest to take a look at http://loadzen.com (full disclosure: I’m the founder). The site offers cloud based web load tests and has a a strong focus on removing the complexity from ceating meaningful load tests. The main feature being a chrome plugin that will effetively record your whole teting session (including Ajax), then allow you to ‘mix’ your recorded journeys into a meaningful simulation of your real (or expected) traffic.

    We’re new on the block so just want to put our hat in the ring :-)

    Thanks,
    Martin
