What is a good easy to use profiler for C++ on Linux? [closed]

Answer 1

valgrind is a well-know linux profiler

Answer 2

Zoom from RotateRight ( http://www.rotateright.com ) is what I've been using. It has a butterfly view of functions and you can double-click any function to dive into source or asm code. Build with debugging information (-g) to see your source, but you should still build and profile optimized code.

Answer 3

Take a look at Sysprof. You distribution most likely has it available already.

Note that all of the mentioned profilers work best if your application is compiled with frame pointers. That is, you should use -fno-omit-frame-pointer on the gcc command line.
