(RADIATOR) Performance and Tuning.

[Hugh Irvine]

Hello Julio -

The only way to verify what is going on is to set up Radiator with a 
LogMicroseconds logger (requires Time-HiRes from CPAN) and check the 
time that is being taken for the various processing steps.

A Radiator configuration with 350 Handler clauses is not going to 
perform terribly well and you can probably optimise your database as 
well.

In almost all cases that I have looked at the bottleneck is the 
database, so you should check a trace 4 debug from Radiator as 
described above together with the performance and tuning data from your 
database.

BTW - the largest operation that we are familiar with uses 6 frontend 
Radiator hosts that are load balanced, operating against a very fast 
Oracle backend server. This setup has been tested to 1200 radius 
requests per second.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
