A friend of mine engineers at intel and told me the Xeon is
in fact 400mhz, split into 200mhz for each cpu on the front side bus.
so its only 66mhz slower than the amd which runs 2 independant 266mhz
front side buses.
I found an article by Rick Gerard. he had the same problem. It was the IDE Drive controller.
These units ship with 15,000 rpm hard drives and thats what your supposed to use with them.
AFter running some software benchmarks, the XEON was only slightly slower (less than 10% on most tests) than my pentium 4.
But on the disk read/write tests the P4 beat the Xeon by 60%…..Bottle Neck found! 15k rpm drive on the way! 🙂
