I would think that a qpsmtpd system might not be able to handle as
much throughput as a stock qmail system, due to the amount of up front
processing that it does. Obviously, each qpsmtpd system is going to be
different, depending on what plugins admins choose to use with them.
I currently use a dual Operton 244 system with 64 bit FC3. Dual
hard drives (mirrored) using a 3WARE SATA controller. qpsmtpd 0.32
forkserver.
For some 600 users, I am only seeing an average of 15,000
transactions per day. The load average is usually between 0.0 and 0.1, but
will occasionally reach towards 1.0 if there are many simultaneous
connections, plus some heavy resource cron jobs running at the same time.
It is conceivable that I might have to host up to 10,000 users, in
the near future.
I am wondering if someone else has similar hardware, what kind of
a userbase they are supporting with it. Similarly, if someone is
supporting about 10,000 users, what hardware they are using.
Thanks.
