Use ValgrindValgrind, callgrindCallgrind and kcachegrindKCacheGrind:

valgrind --tool=callgrind ./(Your binary)

generates callgrind.out.xfile callgrind.out.x. Read it using kcachegrindKCacheGrind.

Use gprof (add -pg-pg):

cc -o myprog myprog.c utils.c -g -pg

(not so good for multi-threads, function pointers)

Use google-perftools:

Uses time sampling, I/O and CPU bottlenecks are revealed.

Intel VTuneVTune is the best (free for educational purposes).

corrected obvious typo, added detail regarding replacement of Codeanalyst with CodeXL
