Interesting that http://developer.yahoo.com/yslow/ itself gets an F grade with YSlow

Looks good, but you shouldn't put equal weight on all the categories. Profiling something slow (a program, a site) means figuring out what's killing you and fixing that. So don't worry about getting an 'A' grade from this thing for checking all the boxes.

Quick question.. has anyone looked into how much it costs to put your JS/CSS/img files on a CDN? Do big CDNs like Akamai even consider small-volume startups?

[benhoyt]

That is sweet. Typical -- google.com gets an A for everything. :-) The Stats tab showed me immediately the importance of an Expires header.

This is just a big ad for CDNs

Neat. My companies website mostly fails despite feeling quite fast subjectively though.

Did anybody find the download link?

If you can't see the .xpi link, you could try https://addons.mozilla.org/en-US/firefox/addon/5369 which is what the page links to anyway. More specifically, https://addons.mozilla.org/en-US/firefox/downloads/file/1783... (have Firebug installed first).

Thanks! What is an .xpi link, and why would I not see it?

It's an extension for Firefox, and other XUL applications too I think, and you shouldn't see it because the browser should detect it and do something with it?
