I've had good experiences with -Os, which appears to be a good selection
of optimisations suitable for real-world use. Apple use it routinely for
OSX, for example. I gather that for some code it's actually faster than
- -O3 due to better cache utilisation when not unrolling loops.

If you're non-commercial you may also want to look at the Intel compiler
suite, which can be free, and is (I gather) much better than both gcc
and MSVC.
