Even our 4-way P6 200 machines could keep 40 MB/sec sustained (easily)
over 32-bit 33MHz PCI busses, so I'm really hoping it shouldn't be
difficult for 4-way Xeon's to get at least 80 MB/sec over 64-bit 33-MHz
busses. (or at least approaching that) Question for the list (well,
lwz@dandelion :) - Can the DAC1164P sit on a 64-bit 66 MHz PCI bus?
My performance staying the same (and in some cases slightly better)
in the 1-way Xeon case really frightens me, esp. when CPU util in both
cases stays well over 98%
