I've upgraded my main FreeBSD box to 4.3-RC and have found a curious result. It's not crashing, or corrupting anything, or running slow, but it *sounds* really annoying. When I use "cvs update" to refresh my -current, -stable, and ports trees, disk activity clearly pulses once every second. Previously (with 4.2-R) this was not the case (or perhaps it was very faintly underneath the other disk activity). I'm finding this "pulsing" quite irritating, and am willing to sacrifice a lot of disk speed to be rid of it. Which sysctl options, if any, can I use to prevent synchronised once per second pulses of disk activity? Possibly useful hardware hints: K6-2/300, MVP3 chipset, 96MB ram, ncr875 scsi, multiple IBM UW disks (one has the CVSROOT and another the checked out source trees). I update the source trees one at a time. Stephen. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
