Website Speed Tests

To test your website's speed, it's a good idea to make sure it's not just your local internet that's causing the issue. By using website speed tests, you can verify other connections are having similar issues.

If you're using WordPress®, you can try Troubleshooting Common Issues in WordPress. W3 Total Cache is a performance optimization framework for WordPress, that is designed to work in any type of Website or web hosting account.

You can also use free third-party tools to troubleshoot the cause of your Website's slowness and to make a plan for your next moves.

Using WebPageTest.org to Determine Website Slowness

Using Webpagetest.org you might be able to determine the cause of your Website's slowness.

To Use Webpagetest.org to Determine Website Slowness

  1. Go to Webpagetest.org.
  2. Enter your website's URL.
  3. Pick a test location near your server (North American customers, pick a server in North America. European customers, pick a server in Europe. Asian customers, pick a server in Asia).
  4. Select your browser type from the list.
  5. Click Start Test.
Things to look for:
  • If you see First Byte is slow (longer than 1 second), it indicates slowness at the server itself. This could be because of your Website's program code or plugins.
  • If you see a high number of Requests (more than 100), then your Website requires the browser to make a lot of connections to display your Website's content. Try to display less content from third-party Websites, combine JavaScript and CSS files, use CSS sprites, and enable caching headers to make the browser do less work.
  • If you see a high number of Bytes in (more than 1,000 KB), then your Website requires the browser to download a lot of files before it can display your Website's content.
  • If you see an F for Compress Text, you should try Enabling mod_deflate with Your Hosting Account.

You should repeat the test several times over the course of 10 - 15 minutes to get a more accurate representation of your Website.

Using Google PageSpeed to Determine Website Slowness

Using Google® PageSpeed, you might be able to determine the cause of your Website's slowness.

To Use Google PageSpeed to Determine Website Slowness

  1. Go to PageSpeed Online.
  2. Enter your website's URL.
  3. Click Analyze.
Things to look for:
  • If your score is an 85 or lower, you have some work to do. Regardless of what's going on at the server, your Website will load slowly in the browser.
  • If your score is an 86 or higher, your Website is probably doing well in the browser, but you might still want to investigate with other tools.
  • In the Suggestion Summary, look for High Priority. This is a customized report for your Website and each item has a list of the resources on your page that can be optimized as well as some general information on how to optimize them.
  • In the Suggestion Summary, review the section labeled Already Done!. This report suggests guidelines to follow to ensure your Website is in line with common best practices.

Using Yahoo! YSlow to Determine Website Slowness

Using Yahoo!® YSlow, you might be able to determine the cause of your Website's slowness.

YSlow requires Firebug to function. This plugin is also incompatible with Firefox® 5 and above.

To Use Yahoo! YSlow to Determine Website Slowness

  1. Install the Yahoo! YSlow browser extension or bookmarklet.
  2. Go to your Website.
  3. Open YSlow or launch the bookmarklet.

    On some versions of YSlow you must click Run Test.

  4. View the results.
Things to look for:
  • Go to the Grade tab. YSlow creates a customized report for your Website. Each item has a list of the resources on your page that can be optimized as well as some general information on how to optimize them.
  • If your score is a C or lower, you have some work to do. Regardless of what's going on at the server, your Website will load slowly in the browser.
  • If your score is a B or higher, your Website is probably doing well in the browser, but you might still want to investigate with other tools.

Using Pingdom Tools to Determine Website Slowness

Using Pingdom, you might be able to determine the cause of your Website's slowness.

To Use Pingdom to Determine Website Slowness

  1. Go to Pingdom Tools.
  2. Enter your website URL.
  3. Click Test Now.
Things to look for:
  • If you see a large page size (more than 1 MB), then your Website requires the browser to download a lot of files before it can display your Website's content.
  • If you see a high number of Requests (more than 100), then your Website requires the browser to make a lot of connections to display your Website's content. Try to display less content from third-party Websites, combine JavaScript and CSS files, use CSS sprites, and enable caching headers to make the browser do less work.
  • If you see any 4xx or 5xx errors on the Page Analysis tab, that means your Website is referencing a URL that doesn’t exist (cannot be found), or otherwise is generating an error. You should investigate to see which URL is causing the error and fix it.
  • If you see any 3xx statuses on the Page Analysis tab, that means you're referencing a URL that is causing a redirect (an additional request). You should investigate to see which URL is causing the redirect and fix it.
  • Under the Page Analysis tab, if you see a large amount of time spent on another domain under Time Spent per Domain, this means another Website's content could be slowing down your Website in the customer's browser. You should investigate this further.
