I think you don't understand how request protocol can be simulated by hammering with our tool. We have tested various protocols by this tool.<br><br>Per our test results, radius can reach the limit of requests by hammering easily but CPU was still low. We have various statistics on all these. My point is that radius was not able to use full cpu resource until reaching max number of handful requests.<br><br>Your point with more clients does not make sense because we already reached max reqeusts hammering by our tool and that was same regardless of adding more clients under multi-threaded enviroment.<br><br><div style="font-family: times new roman,new

IĒve had 10 multi core boxes hammering one server, still not enough .. You need more clients .. ;) RADIUS as such requires very little from the server side in terms of CPU. All it really does is compare x with y and then respond yes or no, once you strip down all the various variants of auth protocols. ThatĒs not a high requirement. IĒm confident if you use a SSL enabled protocol, your CPU on the server is spending more time per request doing the necessary SSL stuff than RADIUS related work ..<br><br>
A pint of unspecified beverage says youĒll need more client CPU .. IĒll agree with the pint ..<br><br>

Re: performance report? </span></font><font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size: 11pt;">It is not likely your actually putting too much strain on the server side. YouĒll need quite a lot of machines hammering the RADIUS server before itĒll break into a sweat. The client side would have higher CPU utilization then the server side, per request.<br><br>
Comparing one program to another is not exactly comparing apples with apples. ItĒs more like comparing a duck with a fork lift. One flies, the other just doesnĒt (or rather, when it does, you donĒt want to be there to see it) ...<br><br>

Just noticed that radius cannot reach more than 20% CPU time when we ran a heavy traffic with nas simulations. We have tested some other programs and could reach even more than 90% so just curious anybody experienced the similar result.<br><br><br></span></font></font><font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size: 11pt;"><br>
