weeb page peformance testing

WebPageTest is my favorite website performance tool for quickly testing what is wrong with a slow loading site.  The tool includes waterfall charts, compression and caching testing.  Best of all you can run both initial and repeat views as well as run multiple tests to average out results.

Waterfall charts break down each individual component so you can spot what’s slowing down your site.

Waterfall views help you pinpoint what components may be causing your site to slow down. Webpagetest also marks the start render and page complete times which are critical factors in website performance.


This is another excellent tool similar to the one above.    Many people like it because you get your Google PageSpeed Grade and your Yslow Grades.  This can make it easy to show improvements to clients.  I recommend this tool if you are mainly looking to improve front-end performance.

WordPress sites often receive low scores on some tests. This is mostly due to themes and plugins adding custom CSS and JS files which can cause a low score.

pingdom moniotring

Pingdom provides excellent monitoring services but they also include a free full page performance testing tool.   The main report is a waterfall view your sites load times.  They also include some scoring.   This performance tool runs very quickly, so you don’t wait long for the results.

Also, I find the report layout easy to use.  They make it very easy to grab response headers on a per HTTP request basis.  This can be beneficial if you are fine tuning HTTP response headers to improve performance.



This tool has been around for ages, but is very useful if you need to test from multiple locations.  There’s probably more than 100 locations available to choose from.



Relatively new with tons of features.  They like to break tests down into small parts.   The results are very similar to Google’s page speed but the layout and ease of use is great.

They link each poor test result to an explanation about why it is important.  This is great when you have to explain an issue to someone not familiar with web site performance optimization.

Feedthebot has many interesting tools. Best of all each issues is liked to a simple description of the problem. Will be a great resource in helping explain web performance optimization issues to customers.
