more children will help - alot of this is suck it and see as
performance can vary alot. normal starting point is 5 children per
core and 30 messages per batch.
for that sort of level I'd be looking at multiple machines - if you
loose this machine or whatever reason what happens!
Also check the RBL's you're running - things like spamhaus will
require a licence for thsi sort of amount and too RBLs slows the
processing down alot.
