 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. 

 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.

 Any other ideas, besides buy ia-64 hosts? Thanks.
