What arguments are you using for radperf? -n doesn't really work.
-p will send requests as fast as the server can handle them, but no faster. So if oyu're using "-p 10", and only seeing 15 pps, it's because the server can handle only 15 pps.
Ok. RTFM is sometimes helpfull. I am using radlcient with -p 10 now from a remote host: radclient -s -p10 -f seppel <IP of radius-server>:1812 auth testing123 -q 175sec Total approved auths: 19762 Total denied auths: 964 Total lost auths: 0 Gives aprox 118 req per sec, system load on radserver < 1 with -p 25 Gives aprox 283 req per sec, system load on radserver > 5 For a virtual host with database and radius on one machine, it should be ok. I will test some day with a real database server. BR Uwe -- kiste lat: 54.322684, lon: 10.13586
