I have been using mailman+sendmail on a CentOS Linux VPS box, with 2 x Intel(R) Xeon(TM) MP CPU 3.66GHz CPUs, and 2 GB RAM. The list is of around 65000 users.
Form the past few weeks server seems to be very slow in delivering mails. I have been receiving mailer approximately with 2 hours delay.

And presumably the "last" users have been seeing over 8 hours delay.
Also, possibly Mailman's out/ queue is backlogged.

That's still too long to be viable.
Can you please suggest me how to improvise the performance of mailman
Go to the FAQ at <http://wiki.list.org/x/AgA3> and search for "performance".
or how about if I want to migrate the mailman from Sendmail to Exim ?
See <http://www.exim.org/howto/mailman21.html> for information on integrating Exim and Mailman
