Re: Fastcode CharPosRev B&V 0.4.0

Hi

Interesting results ;-)

All processors benefit from unrolling.

Opteron benefits most, but the curve has some weird bends. This is probably
due to misalignment of the branch target when execution breaks out of the
loop. Opteron could probably benefit further from unrolling, but the other
processors will benefit only little from going about 9 times unrolling.

Both Prescott and Northwood are running at 2800 MHz, but Northwood is much
faster.

Dothan is sligthly faster than Yonah at the same clock = 1733 MHz.

Opteron is slowest but it runs at 1400 MHz only.

Best regards
