It depends, as always. I think the delay may be related to the DNS error.
Whatever time you do see will break down to a "large" per message overhead
with a "small" per recipient time - in other words, just because to send
to one recipient takes X seconds does not mean 100 reipients will take
100X seconds.

How much traffic?

You should be fine. I'm running mailman on a "half-dome" iMac - two major
lists - one has about 50 members and gets 100 or so small (under 5k)
messages per day and the other has about 150 members and 1 100k message
per day. DSL at 384kbps upstream. I don't notice the effect of either list
on computer performance. I would notice the second on DSL bandwidth if I
were up at 2am when that message gets sent - it ties up the connection for
about five minutes (I VERP all messages so to send to those 150 members
means 150 seperate messages going up the DSL line).
