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
