performance report?

[Kevin J]

Well, Radius protocol is not just machine-to-machine issue.  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.

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.

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.

Re: performance report? I still do ...

I’ve 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. That’s not a high requirement. I’m 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 ..

A pint of unspecified beverage says you’ll need more client CPU .. I’ll agree with the pint ..

Well, that's why I am saying we used the nas simulation tool.  We can hammer a lot of traffic with this multi-threaded tool and also we tried at least three client boxes so don't assume our traffic was not enough.

Re: performance report? It is not likely your actually putting too much strain on the server side. You’ll need quite a lot of machines hammering the RADIUS server before it’ll break into a sweat. The client side would have higher CPU utilization then the server side, per request.

Comparing one program to another is not exactly comparing apples with apples. It’s more like comparing a duck with a fork lift. One flies, the other just doesn’t (or rather, when it does, you don’t want to be there to see it) ...

Does anybody know the performance on Sun T-1000?
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.
