FreeRadius Server Sizing recommendations

[Rui Ribeiro]

As said bellow the thread, use benchmarking tools.
I am authentication 15k users in AD (3 times as much of you), Vmware VM.
3-5k daily users and 512-800MB of RAM is more than enough for me for
running FreeRadius (in fact in memory the binaries only use 70MB).  The
detail accounting only grows in the tune of 3GB per month. The MySQL
database is on another server. As for the MySQL server you may need more
1-2GB, so 4GB is more than enough for a dedicated server without bloat and
FreeRadius + MySQL). My CPU requirements are also *very* low, two CPUs load
average: 0.00, 0.01, 0.05.
