I have ~10k users and having some performance issues on my two FreeRadius 0.4 servers. I am using MySQL for radius accounting and LDAP as my authentication methods, along with CHAP. I get consistent messages of the type: Error: Dropping duplicate authentication packet from client, from my research this means we are not answering the radius requests fast enough. When my load is broaching 200, 300, etc, I can understand that. What kind of tweaks do you guys have running to get better performance? Do I just need a more beefy server?
I am running two servers of the following stats: P3 500mhz 256M Same HDD for /usr and /var max_request_time = 15 delete_blocked_requests = no cleanup_delay = 7 max_requests = 900000 (i've played with many different values here) Both running RH 7.X I am in process of building a sparc 20 w/ solaris and a FreeBSD machine to see if I can get better results from them. Any help appreciated. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
