I posted a message some time ago on performance profiling and testing in IE and the best thing available was Firebug Lite which required me to wrap everything in start/end calls.
I've since written a time library to hook functions to reduce the amount of work required to performance test. It works in IE6+, Opera, Firefox and Safari. http://remysharp.com/2007/04/20/performance-profiling-javascript/ In particular, you can attach this to any function, including the jQuery selector function: $ = time.func($); Now when you run $('table > [EMAIL PROTECTED]"user"]') (or a query you think may be unoptimised) it will return the standard jQuery result and log the time taken to execute the selector. Or you can test the functions attached to events $('a').time('click') If anyone has any suggestions or spots and bugs or improvements that can be made, please drop me a comment. Thanks.
