I know I do

Yesterday afternoon, Yahoo! released a nice little tool built on top of Firebug called YSlow (Firefox only). In Yahoo!’s own words:

YSlow measures web page performance based on the best practices evangelized by Yahoo!’s Exceptional Performance team. Since many of these best practices focus on the frontend, YSlow is integrated with Joe Hewitt’s Firebug, the web development tool of choice for frontend developers. »

I test drove the tool this morning and apart from the fact that I got an embarrassing and pitiful F for Youtilize, I still really like YSlow.

YSlow follows YDN’s Exceptional Performance guide for its performance test, which is definitely a great guide to follow. One thing to keep in mind though is that one solution doesn’t fit all, so don’t take the test results too closely to heart.

For example, while I agree I need to minimize my HTTP requests, I don’t think this blog will benefit greatly from using a Content Delivery Network. Other blogs may, but not me. At least not yet

Summary

Use this tool to see if there’s anything you can do to optimize your website, but don’t go crazy over every negative result.

Also, YSlow is a plugin for a Firefox plugin? Weird.
