How to speed up turn processing?

Ok we have a FTP based game server we have set up to play our game. (Spread over the country since collage but still play SE). The entire system is automated and work well. (Even has a GUI front end now) The only issue we are hitting now is with the large number of players and ships (8 computer 4 human) turn processing is taking forever.... (right now sitting at a hour and climbing)

This is a dedicated server for processing turns. I seem to remember that there was a file you could change to speed up the rate the PC computes the turns. Does anyone remember where that is at?

Thanks,
