Even better, use different optimization levels per file and benchmark them.

If you have N files, then that's only 3^N builds to test out each possible combination of O, O2, and O3. That shouldn't take too long. /s

Why stop settle for just -O levels? You could fiddle with all flags that might affect performance. You could even write a program that automates this and employs generic algorithms to reach good results quicker...
