Are you sure about the IE soon part of Sounder's YSlow and how many eons more it will take?
http://pagetest.getrpo.com/ not loading for me in FF3.

Thanks. We rolled the NZ testing into the main site and I forgot to clean up the link here.

Souders doesn't work at Yahoo anymore - YSlow was taken over by a team there and they are actively working on it. They were supposed to be working on a version that would work with IE but I haven't seeen any activity on it for well over a year so I pulled out that comment.

Thanks,

If you are behind some proxy which disables gzip headers, its difficult to check if resources are properly compressed.
Here is a tool which makes it easy http://www.gidnetwork.com/tools/gzip-test.php

FWIW, the hosted pagetest instances are not behind proxies so you will see whatever the server responds with here as well.

I just found http://zoompf.com/ the other day - it's pretty aggressive in the sense that it will crawl your CSS files and warn you about paths in them that don't actually apply to any pages (among other things), but it provides another perspective and another way to look at load time metrics.

Thanks. Just added it to the list. Looks like there may be some gotcha's with using it but more information is always a good thing.

I also noticed that Speed Tracer for Chrome isn't mentioned. While it's not quite as easy as a FF addon to set up, I've found it useful to find hot spots and get a really drilled down view of what's going on as your page renders.

Thanks. Also added dynaTrace Ajax edition. The list hadn't gotten any love for a while and there has been quite a bit of progress on tools.

In your list with Pingdom, I would add : http://site-perf.com/

This site doesn't seem all that reputable...look at the Web of Trust scorecard:
