Optimum Configuration

I am going to dedicate a server to FMS. I plan to have as many as 10,000 connections. Does FMS in linux take advantage of dual processors? Memory? Disk Space? I won't have sophisticated applications nor am I doing media streaming. This is purely for socket/shared object use. I'd liek to know if 4GB of memory helps over 2GB. Is a large amoutn of disk space required and does dual processors help.

Also, from what I understand, I only need ports 1935 and 80 open correct?

Thanks!
