Show Slow is an open source tool that helps monitor various website performance metrics over time. It captures the results of YSlow, Page Speed, WebPageTest and dynaTrace AJAX Edition rankings and graphs them, to help you understand how various changes to your site affect its performance.

ShowSlow.com (this page) is a demonstration site that continuously measures the performance of a few reference web pages. It also allows for public metrics reporting.

If you want to make your measurements publicly available on this page, see the instructions on Configuring ranking tools page. If you want to keep your measurements private, download Show Slow and install it on your own server.

You can ask questions and discuss ShowSlow in our group http://groups.google.com/group/showslow or just leave feedback at http://showslow.uservoice.com
