  No.  You'd have to supply the full details of what you're doing.

  If the users aren't authenticating, the load on the system is zero.

  So the question is, how many authentications per second do you expect?

  Read raddb/certs/README.  There are instructions for testing systems
to see how fast they are for EAP methods with SSL.

  But to be honest... an iPhone 3GS would handle the traffic just fine.
 And be 99% idle.

  i.e. it doesn't really matter what you provision.  Modern systems are
enormously fast.
