What's your favorite profiling tool (for C++) [closed]

Question

So far, I've only used Rational Quantify. I've heard great things about Intel's VTune, but have never tried it!

Edit: I'm mostly looking for software that will instrument the code, as I guess that's about the only way to get very fine results.

What are some good profilers for native C++ on Windows?

Answer 1

For linux development (although some of these tools might work on other platforms). These are the two big names I know of, there's plenty of other smaller ones that haven't seen active development in a while.

• Valgrind
• TAU - Tuning and Analysis Utilities

Answer 2

For Linux: Google Perftools

• Faster than valgrind (yet, not so fine grained)
• Does not need code instrumentation
• Nice graphical output (--> kcachegrind)
• Does memory-profiling, cpu-profiling, leak-checking
