Is there a good way to know which are the sections of my code which take a lot of time ?
I do some I/O reading, and guess is what take most of the time, but I would like to confirm it.
(I do a lot of fgets(), around 1000 times, then split, filter and add this to a graph)

Okay, found a better way, by reading everything at once.
