In reply to Marc.

Marc, I don't have any other specific recommendations other than what the SAS notes already provide. I don't know that these recommendations have changed for SAS 9.4. Since I/O is most likely the biggest constraint, you might run some tests with SASIOTEST.EXE (in your SAS installation folder) to see how your system performs. Run it from a command prompt to see the options available. SAS Technical Support can provide guidance if needed.

I think that the recommended system for SAS 9.4 on Windows Server is a minimum of 4 cores. It can probably work okay with 2, but you might need to tune a bit. Like any system, the performance will depend on how many users and what they are doing.
