You should have 2 main concerns:

how fast can you submit mail to the mail server;
how fast can the mail server deliver it.

I did a mail system performance evaluation and found the PostFIX and
QMail far faster than sendmail. In those tests we used a controlled
mailing list with several destination servers, and we measured how much
time the sender application took to deliver all messages while keeping
track of the mailer daemon message queue size.

I think you can setup some analisys like this by yourself easily. I
would suggest to keep an eye at your DNS setup. Normally it is the
system bottleneck.
