[Mailman-Users] Slow Performance on Mailman, Next Steps?

Dear all,

We moved our mailman list over from yahoo to my server this
week.  No a painless move but it went OK.
(This is some pretty good software!)

My big issue is performance.  Our list has 2300 subscribers and
we do about 20 to 50 e-mails a day, nothing too big.

Messages were taking 3 to 4 hours to be sent.  I went through
the FAQ on performance and have done the following to get down
to 30 to 90 minutes:

1: Put in a DNS server on my machine with caching (pdnsd)
2: Used the following mailman settings: 
3: Turned off the logging

Some other facts:

a: I'm running RedHat 9 Linux
b: We are getting lots of bounces: 258 have been put on hold because they
   went over their bounce score
c: I'm using a 2+GHz AMD machine.  Lots of horse power and it seems like
   I'm not using much.  CPU is sitting at between 5% and 10%

So, my obvious questions are:

I: Any suggestions on my mm_cfg.py settings?
II: Anything else you can recommend?
III: My assumption is that since I'm using SMTPDirect it doesn't
     matter if I use the default stuff that comes with Redhat or
     should I load something better?
IV: Is it the bounces that are my problem?

Thank you in advance for any advice!
