Hello Russell - The first thing to do is look at a trace 4 debug in Radiator with LogMicroseconds enabled (requires Time-Hires from CPAN).
This will show you immediately how long each processing step is taking. The usual cause of this sort of problem is a slow database, probably due to a very large number of records in the accounting table resulting in very long insert times. See section 5.6.38 in the Radiator 4.11 reference manual ("doc/ref.pdf"). regards Hugh On 11 Jun 2013, at 09:12, Russell Fulton <r.ful...@auckland.ac.nz> wrote: > Hi > > We are using radiator (on linux) to collect accounting data from Cisco WISMs > (wireless infrastructure).
