Do you use some tools for that or something?

RDTSC is useful for short times.
The QPC API can also be useful for longer times. Or the "wall clock" for even longer times. I've never felt the need for more than that. |

RDTSCP (since 2010) is preferred under SMP, Naive measurements can be done with *nix sh "time". Others (e.g. DJGPP) have "redir -t". OpenWatcom has wprof. GCC has gprof. Linux has perf and valgrind. Or you may just count calling your heavy routines manually (via extra code).

Yep, windows tools. How visual studio users benchmark their code, maybe they have some good way of doing that.
