For a large-scale mail system, number and speed of CPUs is
meaningless. Amount of RAM doesn't really mean a whole lot. What
you need is disk I/O capacity.
Have you put your entire spool filesystem on solid-state disk, or
at least very high capacity multi-spindle RAID 1+0 arrays with high
speed battery-backed controllers with large quantities of write-back
cache?

as one of many items in the Mailman FAQ that discuss "performance".
Of course, you should also see the others, too.
