	Of course, this doesn't address the issue of MTA performance 
tuning.  I've seen situations where proper tuning resulted in a 
factor of ten (or more) improvement in the delivery times.  See 
<http://www.usenix.org/publications/library/proceedings/lisa97/full_papers/21.kolstad/21_html/main.html > 
and 
<http://www.usenix.org/events/lisa98/full_papers/chalup/chalup_html/chalup.htm > 
for two papers discussing this issue.

	See also my slides at 
<http://www.shub-internet.org/brad/papers/sendmail-tuning/> and 
<http://www.shub-internet.org/brad/papers/dihses/>, and the book 
_Sendmail Performance Tuning_ by Nick Christensen (at 
<http://www.jetcafe.org/~npc/book/sendmail/>).


	If you haven't done your job in tuning the performance of the 
MTA, you really don't have much reason to complain about the 
performance of a mailing list manager with a lot of recipients.
