what bothers me is that the freeradius is handling such a small amount of authorizations, and keeping the processor usage below 10%. (?!) why doesn't it take 90% and do in the mean time more work?

Perhaps the client doesn't send enough requests to make the server busy. How do you make your tests?

thank you for your answer. that might just be it! :-) i have a test client also programmed by a colleague, that starts a number of threads (for each authorization one) that in the beginning wait for a semaphore. after all threads are ready, the semapfore is switched to green and all authorization requests are sent in a burst. maybe it needs some tuning.. anyway, do you know any radius eap-sim test clients that work for sure? regards, r.
