It would appear my recommendation may merely mask (for a short time) a symptom of the root problem, but not solve he problem itself. Wietse's insight seems to show that your IOPS issue is a result of the mail not going out fast enough, and thus the disk is getting hammered by the queue piling up. Wieste is right. You don't need faster storage, but more mails delivered per second so they aren't piling up in the queue. You need a faster outbound path, or multiple of the same. Apologies if my lesser insight/experience clogged this thread. -- Stan
