Yes I did and it made some real differences. I enabled it on /usr as well as /var and mounted /var with the noatime option. Doing not bad for the amount of email it is pushing....thing is this I/O problem never use to be an issue....but with growth constantly happening it has come to a hardware based solution. What I have recommended to the company is a scsi card in that machine with 2 scsi drives.....I will raid 0 then together with ccd or venim and mount it as /var....turn existing /var into extra swap space.....although i may thing of something else...as I don;t think it needs a gig of swap... and that should fix the I/O issue incredibly. Right now I have split up the load also between2 machines so that has helped out incredibly....but systat -vmstat is still always showing 100% disk usage so I will have to remedy the problem. Then I plan on moving all mail back to that one machine and beating the shit right out of that freebsd machine to see what freebsd can really handle. If anyone has some nice newbie docs :) on ccd or venim would be greatly appreciated.
