-Os enables more optimizations than -O, but only those which don't
increase the size too much. -O2 (and -O3) enable optimizations which may
increase the size, this may results in code, which doesn't fit into the
L1 (or L2) caches of a CPU anymore. Not running in the caches anymore
result in a slowdown (if it's critical code).

Bye,
Alexander.
