I'm running FreeRADIUS on a PC with a dual CPU of 2 GHz and 2 GB of RAM. It is working with PostgreSQL database. When I perform tests with radperf, running :

where users.csv file contains 10000 user names with password, I get this output:

I would need a sever able to manage a much greater amount of users ( > 50000, up to 1000000). But for now I'm interested how to get the server working well with ~(50000<->100000) users.
The number of users isn't too important, I suspect.
What matters is the authentication rate (number of auths/sec) and the accounting rate (acct/sec).
You also need to ensure your SQL database can reply sufficiently quickly. This might depend on the number of users, since SQL query performance is a complex mixture of table size, indexing and load.
1000 auths/sec is quite a lot. It implies you need to perform 1000 SQL queries/sec (at LEAST).
I'm not sure this is accurate given the number of failed requests, i'd investigate that then re-run the tests. -Arran
