Less would suggest that the >32 bit machine simply sucks badly. I don't agree with the validity of a clock-for-clock comparison, but if you want to do it anyway, I'll again point to Vincent's numbers: At the same clockspeed, Crafty only gets 33% faster on the 64-bits machine. When you read this, keep in mind that most applications get _more_ than 33% faster on the 64-bits machine. -- GCP
