I'm curious about performance problems. I have a Seagate 1G driven
from an Adaptec 2842 on a 486 running Linux 1.2.8.  My friend has the
same disk and adaptec, the same _driver_ and processor, but a
different kernel and some different hardware.  

On his machine, my disk runs at about 1.4Mb/s character writes, and
2.1Mb/s block writes.  On my machine, it falls to half of that, and
occasionally the character writes fall to about 70Kb/s!!  The
termination is fine, the cable is the same one that we used when we
tested my drive on his machine.  

Is there anything known about the slackware distribution could be
causing this difference?
Thanks,
Ron
