Topic awaiting preservation: JavaScript Profilers & Debuggers - Optimizing JavaScript

Whenever you want to optimize any code a profiler can go a long way to assist in determining actual times and problem areas.

I just started using Venkman in firefox:
Venkman for Firefox: http://weblogs.mozillazine.org/asa/archives/006187.html
Venkman for Mozilla: http://www.mozilla.org/projects/venkman/
This is a great debugger and profiler, but I have some concerns as to its accuracy profiling code.
Anyone know how good it is at profiling? Can the numbers be trusted?

Tito Software offers a comercial package which I have not been able to test yet:

Looks good from the three screen shots though ;-)

Anyone know any other Profilers or Debuggers for JavaScript?
Anyone have any experience profiling or debugging JavaScript and want to share tools/methods with the rest of us?

If so this threads for you.

Thanks!

The Microsoft Windows Script Debugger, of course. I don't know if it supports profiling, though, since I only use it to get less meaningless error reports from iew.
