I stumbled upon a little gem today while searching for a few more techniques to improve the performance of my ASP.NET web applications. I use YSlow and Google Page Speed almost daily, and it was great to find this website that combines the both of them called GTmetrix. GTmetrix combines both Google Page Speed and YSlow into an easy to read, tabbed, table of recommendations. Each recommendation, once expanded, offers you a list of tasks that you can complete to improve the performance of your test. What’s more, is it ranks the grouping of recommendations from Low to High so that you know what to get after first. If you’re serious about your web site’s performance, definitely check this one out!
