Speed up your web pages with YSlow

From the Yahoo Developer Network, YSlow is a handy Firefox/Firebug add-in for getting a grade on the performance of a web page. I had some pages that were making C's, considered the recommendations from YSlow, and now they are Grade A performers. Thanks YSlow!

HttpWatch for IE

I'm a big fan of Firebug, especially the Net tab that provides statistics and information on browser/server communication. Not many similar tools out there from IE, but HTTPWatch comes close. The trial version is sometimes handy, but at $295 for a single license, I haven't been able to balance out cost/benefit of the full version yet.
