early stepping K6-2s did not have an MTRR. later steppings do (i believe
stepping 8 was the first one to have an MTRR... but i can't say for
certain):
my cpu:
processor : 0
vendor_id : AuthenticAMD
cpu family : 5
model : 8

sure I should be able to pull that out of somewhere
from the k6-2:
raid5: MMX detected, trying high-speed MMX checksum routines
pII_mmx : 1121.664

Can you report the xor calibration results when booting them?

Hi
It's most likely due to the current celerons having better memory bandwith
than the K6-2's.
The more data pr. time unit that can get through the memory system the
more time will be spend by the CPU doing calculations instead of sitting
idle waiting for data.
This is one good reason for using

Hi folks,
I did some tests comparing a k6-2 500 vs a celeron 400 - on a raid5
system - found some interesting results
Raid5 write performance of the celeron is almost 50% better than the k6-2.
Is this b/c of mmx (as james manning suggested) or b/c of the FPU?
