I have a C++ program that is slower than I would like. I would like to use a profiler that would tell me in what functions is it spending the most actual time. gprof seems like an interesting tool, but I would like to know if there are other alternatives. The issue is that I have a particular program that is slower under Windows than it is under Linux, and I want to know why that is the case. I use -O3 and g++-4.2 Thanks
