AFAIK to get the real benefit you need it enabled in the BIOS, and you need to set the flags correctly for wdc0/wdc1 accordingly (see the LINT kernel config). > Yes, I'm a SCSI zealot myself, but even given IDE it shouldn't completely > crush network throughput -- it doesn't hurt other operating systems at > all... > > If the 3.1R upgrade and IRQ/BIOS tweaking doesn't solve it, I'll probably > upgrade to SCSI. Did you see my question re. How are you measuring this? - i.e. if your system only has 1 drive, you can't expect great throughput if your cp'ing say a 300Mb file from that drive to another file on that _same_ drive, as well as ftp'ing another large file to/from a remote machine via the _same_ drive? :-) -Kp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
