Then that means for normal ia-32 machines, the PCI&IDE Bus speed
is
mostly 33MHz/s, and so the sustainable IDE disk access speed is always
no more than about 33MB/s? I tried several types of Linux boxes, the
long-time disk access is about no more than 35MB/s.
Which current IDE hard disk do you expect to have more then 35MB/sec to
50MB/sec sustainable speed? Do not mix maximum possible bus speed with
what you can expect from a drive in real. An remind that manufacturers
overstate with specs given for their products.
And there are no other means to accelerate disk access speed?
Manuauly
setting IDE disk's access mode (UDMA2/3/4/5/6) with hdparm has no big
difference, as far as from my own experience.
Normally that really makes no real difference. Only for cases where the
disc can deliver data from their cache.
Any other ideas, besides buy ia-64 hosts? Thanks.
Why should IA64 change anything? The disk itself is the limiting factor.
