Description Steve Timm 2000-08-22 14:11:29 UTC

I have RH 6.2 Kernel 2.2.16-4smp on a Dell Poweredge 2450
2x600 MHZ, Adaptec 7899 on-board Ultra160/m SCSI controller,
3 Seagate SCSI drives (10000 RPM Cheetah), 1 9gb, 2 18 gb.

Problem arises when measuring block read and write disk 
performance with "bonnie"  Rates seen for write are
between 2-10 MBytes/sec.  The drive and the bus should both
be good for 30 MBytes/sec, and do perform that well under
different operating systems.  I have tried all kernels between
2.2.13 and 2.2.16, all versions of the aic7xxx driver between
5.1.22 and 5.1.31.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
