Tonto, if you have a k6-2 or k6-3, that's about the best that is possible. The FPU (floating-point) performance of those processors is markedly inferior to even a Pentium PRO. The K7 has a superb floating point unit (about 33% better than a PIII) and as such performs well in AH.
Your only solution is to try drivers until you find the one that performs best. You can also add RAM to your system. (If you have more than 64MB this won't make much of a difference though.)
For more info, check out the AH FAQ file. There's a section in there about how to optimize your system.
