If you're doing a lot of system calls and have a lot of processes
interacting, use oprofile, as mentioned.

For standalone programs, try the Google perftools profiler [1]. It
does statistical sampling at run-time, and produces very nice summary
images showing not only what the hot spots are but the stack traces
that led to them. It can also list your source code with annotations
showing which lines or assembly instructions were the hot spots.

And the same interface works for profiling memory
