I've got a AMD486DX4100 with an Adaptec 2940 and two SCSI drives. When I run iozone on one drive I get about 1.9MB/s, but when I run a iozone on each drive I get about .9 MB/s (roughly half). Since the SCSI bus runs at 10MB/s per second, the limiting factor appears to be the CPU? I thought PCI devices required very little CPU time? Tom
