Dear Stefan,
notes : Freeradius 0.9.2 (with some patches (by Nicolas Baradakis) + mysql Debian woody PIII 1Ghz/ 1G ram , scsi
We can easily support more than 400 req/sec by server, with users in mysql DB , multiple realms , and multiple huntgroups .
Note that performance are falling down when we use a radius proxy to load-balance our home radius server (i still not try the new cvs snapshot) so we decide to use a LVS box to load balance the traffic .
Nicolas Baradakis send a mail with a short description of the architecture , (since this mail we just change proxies by LVS)
http://lists.cistron.nl/pipermail/freeradius-devel/2003-December/006469.html
with this kind of network we can reach more than 600 req/sec without any drop .
if people are interested by more details about the stress of freeradius . let me know.
Regards Thomas MARCHESSEAU Sitadelle Team

Gurus,
I'm not sure, how performant a Freeradius can be build up.
Would it be possible, to set up a system, which is able to support a peak load of 500+ Access Requests/s for a time frame of about 15 s?
As my users are stored in an LDAP directory (which does support about 1000 queries/s peak) the requested configuration must lookup the user there.
Also, the system must be able to assign the IP addresses for the users.
I will have to build a database, to store all RADIUS sessions to be able to retrieve for actual and past sessions.
As of my knowledge, the main performance issues are the Database, the IP address assignment and the online database replication (for fault tolerance reasons).
Is there anybody, who has build a system like that? What kind of HW do I need (wee will need 99.9999% system reliability)
BTW: somebody in my company told me, it would all fit in a 'pizza box' ... which should mean a small SUN System.... How far is he away from the reality, beside the fact, that this would not meet our fault tolerance requirement? rg. Stefan
