We've tried hosting freelancer on a dual 1.9ghz athlon machine with 1gb ram but the server had massive lag issues. After closer examination we found that the game was splitting the usage to both cpus even if the first wasn't 100% and made multiple threads continously recreating and swapping threads causing the lag we experienced. We're running it on a 2.4ghz P4 machine now but due to cpu consumption issues it can barely hold up to 24 people.

Does anybody else have a problem with running a server on dual cpu machines? If not any ideas on how we could resolve this problem we encountered on ours?
