General observation: There are quite a few more optimizations that can have
*some* impact on performance. Options for processor specific code and
increased math speed.
Note also -O2 is not maximum optimization, -O3 is:
-O3 Optimize yet more. -O3 turns on all optimizations specified by -O2
and also turns on the -finline-functions and -frename-registers
