(RADIATOR) Re: Radiator issue

[Hugh Irvine]

Hello Sergio -

The answer to your question depends entirely on how fast your SQL  
database is performing.

I am guessing that Radiator was waiting for the database inserts to  
occur.

You should have a look at a trace 4 debug from Radiator with a  
LogMicroseconds logger (requires Time-Hires from CPAN) to see how  
long each processing step is taking. A very good place to start  
improving performance is tuning the database and running two  
instances of Radiator - one for authentication and the other for  
accounting. This is very simple to do with a single configuration  
file, passing in the relevant parameters to radiusd on the command  
line. This has the great advantage of separating the authentication  
processing from the accounting processing, spreading the processing  
across both processors.

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?
