The profiling results were very close: 84% (gprof) vs. 80% (Valgrind) of call time spent in one method. Both reported the same overall issue. Valgrind also listed other methods, but they primarily lead up to the actual performance culprit. Overall, I felt gprof provided clearer results. The biggest difference, however, was performance. With gprof, the application runs normally; I couldn't visually observe a noticeable runtime difference compared to when profiling is disabled. With Valgrind, it’s like playing a game at 2 FPS vs. the normal 60 FPS. It is nearly unusable in comparison.
