there are various ways to distribute load over multile cores on radiator by 
fanning processes out to multiple radiator instances.

But before getting into that we need to understand a lot more of your setup.

You seem to have a quite simple proxy radius configuration.

I have had setups with high load where a single frontend radiator process has 
distributed eap radius requests to multiple backends for cpu intensive eap 
processing with the Farming feature.  In those cases the frontend has had no 
trouble at all to keep up with the load.

I do see though that your radiator process seems to have high memory 
consumption over 100MB in your screenshot.

That makes me wonder how responsive the backend is that you are proxying to.

Radiator needs to keep track of all the requests it has proxies to the other 
host so if that host cannot keep up with the load a queue will build up on the 
frontend and it will start resending which will cause even more load on the 
backend.  So generally if the backend cannot keep up things might go down the 
hill quite fast.

Not sure if this is your issue. That would need further investigation.

Please tell us more about:

1. the type of requests you are handling
2. the type of the backend you are proxying to

[RADIATOR] 100% load 1 cpu core

Hello List!

After installing Radiator on the test server, I got a problem with the 100%
load 1 CPU core but the others are unused.

Hello -

What are you using to test?

And you should note that a single instance of Radiator is single-threaded and 
will only use 1 CPU core.

At the very least you should run separate instances for authentication and 
accounting.

regards

Hugh
