[Mailman-Users] Return to performance

[Eric Miller]

Thank you all for the suggestions and references.
I made some quick changes, especially the

O Timeout.iconnect=5s

sendmail option seemed to really help. I'm down to 4 to 10 minutes
with most messages at 6.

One question:  Should I be looking at a better MTA?
What is the fastest that works with RedHat 9?
(I guess that is two questions...)

Thanks!

Eric

	For MTA performance tuning issues (especially sendmail), see my 
paper <http://www.shub-internet.org/brad/papers/sendmail-tuning/>, 
Nick's paper <http://www.jetcafe.org/npc/doc/performance_tuning.pdf>, 
and and Nick's book <http://www.jetcafe.org/npc/book/sendmail/>.

	For issues with regards to tuning the performance of mailing 
lists in specific as opposed to MTAs in general, see 
<http://www.usenix.org/publications/library/proceedings/lisa97/21.kolstad.ht

and
