I have a mystery for you folks. Consider this situation:
a Compaq Prolinea 575 (75mhz Pentium)
24mb ram
3gb of "oldish" Seagate Disk on a Buslogic 946C
and a
Micron P90 Powerstation,
64mb ram
Adaptec 2940
And a brand new Connor drive
IOZONE rates disk access for the two systems at virtually the same (+- fudge)
IOMem gives the compaq 10mb/7mb while its 10mb/20mb on the Micron
Doing a time make of a specific configuration (kernel build) takes 9:30 on the
Micron, but on the Compaq its only 8:30. Same exact config/source (brand new
2.0.5-A installs). Nothing else is going on on either boxes.
Can anyone explain this to me?
