Google releases Page Speed [LWN.net]

Google has announced the release of its Page Speed tool under the Apache license. "Page Speed is a tool we've been using internally to improve the performance of our web pages -- it's a Firefox Add-on integrated with Firebug. When you run Page Speed, you get immediate suggestions on how you can change your web pages to improve their speed. For example, Page Speed automatically optimizes images for you, giving you a compressed image that you can use immediately on your web site. It also identifies issues such as JavaScript and CSS loaded by your page that wasn't actually used to display the page, which can help reduce time your users spend waiting for the page to download and display."

Y!Slow is ridiculous. It will give your site an "F" grade for not using Akamai, even if your site loads in a fraction of a nanosecond. It's just a silly checklist. The new Google tool doesn't have binary rules of thumb like Y!Slow and it gives some very detailed info.

The strange thing is I went to the session "Even Faster Websites" at the Google I/O conference last week and they didn't even hint at the existence of this new tool.

Perhaps they are a little embarrassed that it runs in Firefox rather than in
their own browser, Chrome?

One visible difference is that it seems to have tools to help you do something about it right there, like the image optimization stuff, where YSlow just tells you "go optimize your images", if I remember correctly.

Pretty charts, and pretty good diagnostic. The pie-charts of content volume for some sites may frighten you.

Tests any public site for you (on their machines). From AOL, apparently. Just noticed they also have a desktop version (see homepage).
