Re: Performance problem


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
           options.
