whats a good, free program for profiling on a intel windows xp, visual studio express 2008. i have VTune, but it runs out after 30 days.
it only has to be a simple profiler so that i can find where the majority of my code execution lies.
But both of those solutions involves instrumenting the code, which is often unpractical for large projects.
For Linux I would recommend oprofile, but there is no such tool for Windows.
There's kernrate for WinXP and above, which despite its name, profiles user code too. Here's a quick intro, though there's a readme in the package as well.
