RAID controllers and good disks are expensive. If swapping is using up a so much disk bandwidth that it might require a dedicated channel, then you might want to make sure you have enough RAM first. > Perhaps put the /tmp or /usr/tmp on that? hmmm or ram disk? > > > Cheers, > > > -Alex Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
