I have an SMP machine (dual PII 400s) running 2.2.16 with one 10,000 RPM IBM
10 GB SCSI drive
(AIC 7890 on motherboard, using aic7xxx.o), and four various IDE drives. The
SCSI drive
performs the worst. In tests of writing 100 MB and sync'ing, one of my IDE
drives takes 31 seconds. The SCSI drive (while doing nothing else) took
2 minutes, 10 seconds. This is extremely noticable in file transfers that
completely
monopolize the SCSI drive, and are much slower than when involving the IDE
drives.
After a large data operation on the SCSI drive, the system will hang for
several minutes.
Anyone know what could be causing this? Thanks.

Attached are some data to help.
