First, you have a very lightly loaded machine, and it's goofing off
most of the time ;-) This explains the 1.9 messages/min. We've had
qmail do 1000/min on simple hardware, admittedly with ideal recipients.
The queue time includes deliveries that were repeatedly deferred (host
unreachable, user over quota try later, etc) that then finally timed
out their queue life time(something like 7 days). Thus, the average is
not very useful.
Average ddelay per success (s): 95.132936: This shows you that the
delivery attempts that were successful took on average 95 s to
complete. This does not count all the unsuccessful delivery attempts.
Look at other stats in the package. The time taken to complete 50% or
80% of the deliveries or the average time for the first 50 or 80% is a
much more useful measure.
In summary, looks ok and the numbers are a reflection of the
recipients, not your qmail installation.
