Apparently not.
We are running Qpopper 3.0 in server mode and hash spool mode 2, splitting
the mailspool over four partitions located on an RSM-2000 (A3500) Sun Disk
Array (RAID5) while the temp dir is found on an internal dedicated SCSI disk.
Iostat and sar figures do not hint at a particular I/O bottleneck.
The system (E4500, 6 proc@250MHZ, 3 GB RAM) handles in excess of 220,000
POP3 queries *per day* for about 20,000 users. One finds between two and
three dozen Web browsers simultaneously active as well. (There is some
IMAP4 activity but that only accounts for minimal use of system resources.)
We're pretty pleased with its performance.
Eric.
