i have inherited the administration of a radius server, that authenticate 900 PPPoE user on mikrotik box.
i've noticed that there is some performance problem, mikrotik box show that "last request RTT" in some cases is up to 1000ms, there is some "resend" request and also some "timeouts", In order to mitigate the problem i've disabled the interim update, and the timeouts are drastically reduced. But exists.
A 386 should handle 900 users without a problem.
i' use mysql back-end, i've checked if there are slow queries but file is empty. ( of course is enabled... )
<shrug> Performance issues are almost always the DB.
the server is a dual core Xeon 3.0Ghz with 1 Gb of ram. The SO is debian Linux stable, freeradius is 2.1.10 installed by debian package.
So it's not the RADIUS server which is the problem. That amount of CPU power is more than enough.
Any ideas?
Fix the database. If you don't think it's the DB, configure a test server on the same machine which doesn't use the DB. It will handle 2000+ packets per second. Alan DeKok.
