Sysprof is a sampling CPU profiler for Linux that uses a kernel module to profile the entire system, not just a single application. Sysprof handles shared libraries and applications do not need to be recompiled. In fact they don't even have to be restarted.

Just insert the kernel module and start sysprof.

This + oprofile and opannotate are possibly the neatest tools I've found to figure out what's going on w/ codey-McSlowy.
