That is probably your problem. Your bus is only 66 mhz. You are not able
to access your memory as fast as you want to process the data. I once
upgraded a 486 100Mhz to a 486 150Mhz (I think, it was a while ago) and
there was almost no change in the speed. I overclocked the memory bus from
66 to 75, and lowered the multiplier (so the CPU was at the right speed) and
gained more of an improvement. You may have to buy new, faster memory to
make this possible, but the stuff is CHEAP right now. (just bought 128MB
PC-133 Cas 2 for $30!) Good luck!
