Moved to freeradius-users!!

The number of users is not the major factor. Rather the number of 
requests/sec.
Where are the users stored (plain text, ldap, sql)?
Do you perform heavy accounting? To sql?
How many logins do you expect per second,hour,day?
Will you use EAP? If yes will you use one of the SSL versions 
(TLS,PEAP,TTLS)?

In general freeradius should not have any problem as long as you set the 
thread and/or ldap/sql connection pool parameters large enough for your 
specific setup.
The most important thing to check is your authentication and accounting 
database not radius itself. Any modern server should be more than 
adequate for freeradius.
So check the directives in thread pool { }, the num_sql_socks in 
sql.conf and ldap_connections_number in ldap { } (if you are using ldap).
