I have seen something which may be related to this, but I haven't said anything because, well, because I was going to look into it more and then I forgot about it... In my case, the problem is when copying huge files around. I use vmware, and virtual disks in vmware. When creating a new virtual machine, I sometimes just copy a "virtual disk" (a 1-gig file) to a new name, and use that as the starting point for the second virtual machine. While that copy is happening, responsiveness of the system nosedives. System is a dual-CPU 650 MHz p3, the disk is on a ATA controller. Softupdates is on. I figured that copying a 1-gig file is probably a rare event, so I didn't consider it too important to investigate. I have done several buildworlds on this system without noticing a problem, but that may not mean anything. I have enough machines in my office that I can do a buildworld on one, and keep myself busy with other projects on the other machines. Responsiveness could be pathetic and I wouldn't know about it... If this *is* at all related to what you're seeing, I know this was happening to me before 4.2-release. -- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
