Not going to stop the server, but it stops it from hitting its full potential. How many users? I have a server with about 80 users and my averages are; Average: all 6.00 0.00 3.65 3.95 86.40 That is with 2 dualcore XEON's at 2.2 Gh and 4 gigs and a SATA raid 5 (3ware).. It was on a single drive for a month or so after a recovery and I had IOwaits like yours. System was sluggish. Users whined. It wasn't pretty. The single drive was the fastest recovery while I had to replace some drives that tanked. I have a spare, but not 3. -- MailScanner is like deodorant...
