gcc has an address and thread sanitizer built in these days.

    gcc -fsanitize=address ...

    gcc -fsanitize=thread ...
They perform better than valgrind.

This article refers to valgrind's profiling features (callgrind) and not its more common/popular 'memcheck' feature.

Sanitizers and memcheck are unrelated to the profiling discussion here.
