I assume you're talking about specifications for the 
director.

o SMP doesn't help (see HOWTO)

o the director is a router only (with slightly unusual 
rules). All it's doing is routing. If your proposed hardware 
can handle the network throughput, that's all that's 
involved. You only need enough memory to run the OS and 
handle the connections. I don't remember how many 
bytes/connection but at 0.5M connections, that would only be 
a few MBytes of memory
