Safari 4: How to profile the code running when the page loads

Question

In Safari 4, I am trying to use the profiler to see how the time is spent in the code that runs when the page loads.

I enabled the profiler ("Start profiling JavaScript")
I load the page.
I stop the profiler.

At this point, this doesn't create a "profile" snapshot (while it does if I start the profiler after the page is loaded). Any hint on this?

I'm also interested in this. I can profile an action without reload (ie. dragging a google map) but if I start it then reload the page, it doesn't create a profile, what use is that?) — brad, Jul 07 '09 at 18:41

For code inside onLoad handlers, you need to enable the profiler programmatically. Add console.profile() to the start of the relevant javascript, and console.profileEnd() to the end.

It's very similar to FireBug's profiler: Console API

Update: The Web Inspector link above 404s. Here's a more current document: Web Inspector Guide: Timelines
