(RADIATOR) How to do a load test

[Hugh Irvine]

Hello Fred -

The first thing to realise is that "radpwtst" is not a high-performance 
radius load generator, however what we do is this:

	set up Radiator host

	run "radiusd -trace -1 -config_file ....." in a terminal window
	(this will give the number of requests per second)

	run multiple copies of radpwtst on multiple other machines
	(*not* the Radiator host)

The mistake that many people make is trying to run radpwtst on the same 
machine as Radiator which will skew the results significantly.

Otherwise, you can do a google search on radius test generators.

regards

Hugh
