I noticed a substantial drop in CPU usage when I installed the second 256Mb
RDRAM in this system. CPU usage dropped from average 58% at the open to
average 21%, and the average during the day dropped from 26% to less than
10% average. I don't understand why the amount of RAM would affect CPU
usage, but it does.
