You haven't given us much to work with, so it's a wild guess, but I
think you'd probably be able to cut your runtime by half or more.

I recently wrote a multi-threaded postgrey daemon in C as the original
postgrey (written in perl) was taking up far too much CPU.  With high
concurrent load (2000 clients or more), the original postgrey would
easily take 70-80% of the CPU, and I would see lots of timeouts. 
My new daemon takes up less than 10% CPU under the same load and I've
not seen a timeout yet.
