While it is entirely possible to run MDaemon on a Workstation OS, it is not recommended. With that being said, it should still be possible to achieve acceptable performance on a workstation OS as long as the hardware can keep up.
Are you looking at logical disks or physical disks? I’d suggest checking both.
Performance monitor should be able to show you Average Disk Queue Length, Average Disk Read Queue Length, Average Disk Write Queue Length, and Current Disk Queue Length for the logical and physical disks.
Was the issue occurring when the disk queue length was .05? What are the queue lengths when the issue is occurring?
How many users are setup in MDaemon?
Do you have more specific details on the specifications for the hard drives? How many RPM are they? What is the Data Transfer Rate?
Is everything on the machine using a single RAID 1 array?
Ultimately, since I know the software is capable of performing at a higher level, we are simply trying to find the bottleneck. In my experience, it is most often the hard drives. MDaemon is very I/O intensive and often time disks on machines, especially workstations, cannot keep up with the demands when MDaemon is under a load. When the disks can’t keep up it results in slow processing of mail.
