I've thought about this in the past, but I'm not entirely convinced it 
would make much difference. Linux automatically caches the filesystem 
for files which are regularly accessed. For example, see the memory 
graph on my server:


Right now, there's about 1GB of the filesystem cached in memory.

Also there's not much disk io during game play, so the only time it 
would make a difference is during map loading.. but if it's already 
cached in ram, the difference would (probably) be negligible.

Still, it would be an interesting experiment. If I have time I'll try it 
on our server and see if it makes any difference. The entire bf1942 
folder for our DC server is less than 500MB, so it would easily work 
with our 2GB of ram, I think..
