Thanks for your response. As for the pentiums, the answer is definitely
no, they are much much slower, because they don't use risk processors
and the bus is miserable. As for the powermacs or alphas, I don't
really have "empirical" data. Would you happen to know how an SGI
R10000 250Mhz compares to one of these?

Christian
