You will not get a more stable system from softupdates. The system will not become less crash prone with softupdates (on the other hand it probably will not get more prone to crashes either). But you will be able to recover from power outages without fsck having to do much at all as the disks are more clean. All in all: I can only recommend softupdates, specially if you have reboots due to power failures. I do not think the better performance will be noticeable in your case. I have used softupdates on a P133 with 1 10G SCSI-disk and while shuffling files around was some 30 percent quicker my users seldom do large file shuffling and would not have noticed when I turned softupdates on. ---------------------------------- Michael Josefsson, MSEE mj@isy.liu.se This message was sent by XFMail running on FreeBSD 3.5-STABLE ---------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
