Man, that's a BIG machine.  We run on a F30, 166mz 604e, 256M, and 3x2G disks.
That suffices to do 3,000 or so lists, and 30K postings/day generating
several hundred thousand recipients.   With that iron, you should be able
to manage 10 times that load.

This is quite possibly your probvlem right nere.  Listserv does a LOT of
I/O to LSVROOT - if it's slow you're doomed.

Another possibility is a Sendmail issue - I found that for recent
(8.8 and later) Sendmails, using 'FEATURE(nocanonify)' in the .mc
file would give literally a 6X performance boost, with little loss of
functionality (the big loss is that if your machine is called 'lists.psu.edu',
it can't references 'somethingelse.psu.edu' as just 'somethingelse').

Can you tell where the 'lsv' process is spending its time?  I'm willing
to bet it's either busy doing I/O or talking to Sendmail.

Let me know if that doesn't help, or you need more input...
