[RADIATOR] Load testing radiator

[Patrick, Robert]

Running the same tests with a slightly newer server (two quad-core Intel
Xeon CPU 5355 2.66Ghz processors) produces 2900~3000 requests/second,
showing 100% load on one core.  Newer CPUs with greater single core
performance are sure to provide even higher results.

Matthew,

Running a quick test here with no real tweaking supports 2100~2200
requests/second on a server running Radiator 4.4 with latest patches.

Server has four cores total (two Dual Core AMD Opteron(tm) Processor 275
2.2Ghz processors).  Radiator runs at 100% on one of the four cores
while servicing RADIUS requests from three physical desktop clients
(each a 3Ghz Pentium-4) running two concurrent instances of radpwtst,
for a total of six logical clients.  Server had a relatively simple
Radiator configuration providing authentication from a text file.
Increasing the number of logical clients to twelve (four instances of
radpwtst per PC) produced the same results.

radpwtst -noacct -auth_port 1812 -s 1.2.3.4 -secret 'secret' \
 -user guest -password qwerty -iterations 9999 > /dev/null &

Hello Matthew -

We generally use radpwtst.

You should run radiusd with "-trace -1" so you can see the number of  
requests per second.

	perl radiusd -foreground -log_stdout -trace -1 -config_file  
your_configuration_file

	.....

Then you should run radpwtst on a different host and note the number  
of requests per second, then run two instances of radpwtst and repeat.

At  3 or 4 instances of radpwtst on a single host you should see the  
number of requests per second plateau.

Then you should do the same thing on a second radpwtst host, etc.

At some point you should see the number of requests per second plateau  
which will indicate how many requests radiusd itself can handle.

We are available on a contract basis to assist with design and  
implementation of these types of systems.

regards

Hugh

NB:

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive
(www.open.com.au/archives/radiator)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
Have you checked the RadiusExpert wiki:
