I guess you've hit the memory bus' limit. My experience with MacLucasUNIX
is that a fast memory bus makes a big difference in speed with the same
CPU. I've also noticed that a computer with mprime running on both CPUs
on maximum nice level are noticeable slower at running any memory IO
intensive applications at the same time, even when they create virtualy no
extra load. One mprime process goes unnoticed under the same conditions.
