Does anyone have any idea why it takes upwards of 15-20 minutes
(seems longer sometimes) for my postings to this list to get sent back out?

The NSA needs to upgrade the hardware that they use for monitoring e-mail.

Yes, I know exactly why it takes 15-20 minutes for postings to be echoed to
the list.
How is this a problem? There's several reasons why it is set this way, but
if it's a problem for folks that classiccmp reflections take 30 mins to go
out, just let me know.

It can make the turn-around time from question to answer
take over an hour, resulting in time spent twiddling thumbs
at the workbench instead of soldering. Which reminds me...

I suspect that this delay is provided so that one can figure out how to word an
apology for having made an inane comment in the midst of an OT thread. It's
seldom used, though.

Which might be quite nice for users who don't poll their mail more than once
or twice a day, since that prevents snowballing threads from building up over
a day.

It is a non-problem as far as I am concerned, Jay. In some cases I
would not see it 'til the next day anyway.

I'm curious why it's important that it be quick? This is a mailing list, not a
chat room.

The combination of Majordomo and Sendmail is notoriously slow at delivery
to large mailing lists. Majordomo's out-of-the-box setup is to delegate
all of the delivery hassle to Sendmail -- after deciding to forward a
given message to the list, it passes it to a Sendmail process along with a
list of all of the list's subscribers. The Sendmail processs then sorts
the recipients by their MX and runs through the list host by host, one
host at a time, until it's done with the delivery. If it takes a couple
of minutes to do a particular host delivery (i.e. that host is very slow
or it times out), that means that all the machines behind it on the list
are delayed by couple of minutes. The end result is that people at the
beginning of the list get quick turnaround times and people at the end of
the list get variable but generally much longer turnarounds.
Solutions to this problem are 1) not to care, 2) to switch from Sendmail
to a mail transport agent like Qmail or Postfix that parallelizes its
deliveries, 3) to switch from Majordomo to a mailing list manager that
either breaks deliveries into smaller chunks (LISTSERV) or handles
delivery on its own (Lyris), or 4) to patch Majordomo so that it sorts
recipient lists and breaks them into chunks before passing them on to
Sendmail. Majordomo 2.0, which is still not out of beta, does this out of
the box.
Many moons ago (almost 80?) I wrote a FAQ about all this stuff for
comp.mail.list-admin.software, and this particular section is still
relevant. It's at http://www.docnorm.com/mlmfaq.
