bad move, RAID5 is slower on writing than RAID1. RAID5 is great for databases which are 90+% read, but mail is closer to 50/50 read/write. >During the time with high CPU utilization (task manager) I have also >noticed increased Disk Read activity (performance monitor). Just as side >note some of my users have large mailboxes (50 - 200 Mb) there's part of your problem, fix it. >Will second CPU make any difference ? no, your are most likely disk i/o bound, not CPU. Big mailboxes + badly fragmented partitions are causes. put spool, mailbox, and system swap on different partitions.
