[Mailman-Users] Upgrade to version 2.1 - latency on processing incoming messages

the logs indicate that posts are being accepted into the mailman in queue
within a minute from being sent by the MUA.  From the mailman post logs I
can see the messages being sent by out mailman, after which they arriving in
the mailing list members mailbox within a minute. So the majority of the
wait seems to be in the mailman system rather than in the surrounding mail
systems. (Running "qrunner -r Incoming" invariably causes the  mail to much
more quickly.) However I do notice that there is a gap between the time the
message arrives in the in queue and it getting logged in the post log that
accounts for much of the delay
 I can see currently, files in the qfiles/in directory that have been there
for 15 minutes without anything logged for them in either the post or smtp

No this has been reproduced in my test list with two subscribers and small
(< 3k) messages.
