Our mud uses maybe about 10% cpu time.. it's not that as much as the ram..

We have 16 megs on our mud computer here and with nothing else running, 
we never hit swap, without about 1 meg free.. That's with quite a bit of 
areas, etc..

The system we have setup on our mud I think is the best way to do it.. We 
currently have RCS setup, where all the coders for the mud have to 
checkout files, modify them, and check them back in with a log comment.. 
This allows:

1) No one except the person who checked it out can edit it until it's 
checked in and checked out by that person.

2) It keeps logs of all changes made, so if you want to go back to a 
specific revision, look at the log comments and tell it which one to restore.

3) All file permissions are handled by RCS so people can login as 
themselves without having the need for a "mud" account.

We have added quite a bit of areas, and i'd say we take up about 20-30 
megs so far.. Our complete mud is about 4 megs .tgz'd without the binaries..

Hope that helps..
