Maybe this recent addition to 4.16 patches would be helpful too?

Added a new global configuration parameter:

   ResponseTimeThreshold 10

The value is a millisecond threshold for Radiator's response time. If 
the respose time is exceeded, a warning will be loggged.

Here's an example of what it logs:

Tue Mar 15 16:47:41 2016 577739: WARNING: Response time 16.804 ms for 
Access-Request id 236 exceeded 3 ms. (User: 'mikem', Client: 'DEFAULT' 
(default-client), Handler: '' (handler-identifier), Last AuthBy: 'FILE' 
(authby-identifier))

Currently this is a global setting that's not turned on by default.

Alex, you mentioned about logging each request with the processing time. 
Which logfile this should go into?

There's work underway to log just the messages Radiator sends and 
receives. This is separate from the current logging and is more like 
what AuthLog does. What AuthLog logs are the successful and failed 
authentications. The message log will log all messages. The log format 
is configurable. At least text (similar to like trace 5 packet dump), 
pcapng and JSON will be supported.

Thanks,
Heikki
