We are pleased that you are considering Radiator.

The Radiator reference manual is on the web site at:

Radiator is single threaded, however there is a "Fork" option available that 
is limited only by the system resources of the solaris box.

The best tool to use is the "Trace 4" debug in Radiator, possibly in 
conjunction with the "LogMicroseconds" parameter so you can see what 
operations are taking the most time.

BTW - we have many customers with several million users in SQL.

As mentioned previously, Radiator is single threaded, however it is common 
practice to run two instances of Radiator on the same host, one for 
authentication and the other for accounting.

It is our experience that performance issues are almost always related to 
database speed (or lack thereof), or congested links that drop packets.

There are some indicative performance numbers in section 24 of the Radiator 
reference manual.

If you have any other questions, please contact me directly.

regards

Hugh
