I would expect no significant difference wrt performance between CentOS 
and RHEL of equivalent releases.

CentOS necessarily releases behind RH - it has to wait for the source, 
then build, then do its own QA.

OTOH if RH ever makes a serious blunder such that boxes don't boot, then 
one might expect CentOS to dodge that one:-)

Whether it's suitable depends on what the users are doing as much as how 
many there are. if you want help sizing, perhaps you should ask on the 
appropriate RHEL list and/or CentOS.

You haven't said what you expect to do; for me users Scientific Linux is 
better. Like CentOS it's built from RHEL source, but the target audience 
requires additional software packages.
