I could need a few volunteers now to run the benchmark on various
systems and post/mail the results. This would help me in deciding which
routines should be aggressively optimized.
I'd be especially interested in the following systems (but other systems
would be welcome as well):
* Intel Atom
* Intel Core2 65nm (can be recognized by lack of SSE4.1 support)
* Intel Pentium 4
* Intel Core/Pentium M
* AMD K10 - Phenom/Shanghai
* AMD K8 - Athlon64/Sempron
* AMD K7 - Athlon(XP)/Duron
