30,000 messages per hour per single cpu server is pretty good.
I've never coaxed my IMAIL sever anywhere near that level.
I honestly don't see how you are getting IMAIL to do this by
writing to the queue. When I've tried this I have to add an extra
step to initiate a Queue run for IMAIL. Otherwise a message in
the queue just sits there until the next scheduled queue run
occurs.

Take a look at the Perl BulkMail Package by James A Thomason III
available on CPAN or via PPM from ActiveState's repository.
It is available at no cost under the normal Perl license. It can
be extended. It has excellent features including the ability to
retrieve data from a database, dynamic messages on several levels,
universal banned addresses, duplicate handling.
It does handle envelopes so if you don't use dynamic messages then
you can get huge performance increases with envelope sending. You
can certainly get higher performance this way but it only is going
to be effective with ISPs that have lots of recipients in your
list so every list is different. It is good to analyze the list by
domain to get an idea. Hotmail and MSN will not accept multiple
rcpt to's however so you have to have some exception handling for
ISP's (or companies) that restrict addresses in envelopes.
I personally prefer to use Microsoft SMTP for the MTA. If you
want more speed then use several programs and several MTA's with
lots of bandwidth. If you have sufficient resources you give MS
SMTP more connections and let it rip.
I see very little performance hit in using SMTP with BulkMail over
writing to the MS Pickup directory. However, when you put
something in the MS pickup directory it leaves almost
instantaneously regardless how you put it in there.
Using Perl BulkMail and SMTP then allows you to run the program
from MS or Linux or whatever platform you want. If you decide to
use something MySql instead of MS Sql7 then BulkMail doesn't care.
