I'm running 4.0-RELEASE on a K6-2 with an Adaptec 29160 and some IBM DMVS18M drives (nice 10k disks), and am getting absolutely terrible performance. My setup has a Quantum IDE drive in it as well, and I get about 2X better read/write performance on the IDE drive than the SCSI (the SCSI should be a bit faster than the IDE...) I've tried swapping in an Adaptec 2940 to no avail, so it's not the 29160 specifically; I've tried moving the disks to another (Linux) box and the drives work perfectly fine, so it's not the drives/cables. I don't know what else to try, even what other info to send out as diagnostics. Apologies if this is not the right list; I'm running out of ideas, please point me to the right list if nothing else. Thanks a lot. - Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
