Why would you want that many threads?

Can your activemq backend REALLY process > 2048 concurrent active
connections without slowing down? It might be simply that nobody has
tested that many perl threads in FR, so if a lower number works then I
suggest you stick with that for now.

>From my experience with sql, the optimum number of radius threads is
equal to the number of backend connections (in my case, sql). And the
optimum number of sql connections depends on several things, including
processing delay (e.g. network roundtrip between nodes) and available
cpu cores. But even then my optimum number is around 200. If a radius
request arrive when all the 200-threads are busy, it will simply be
queued for later processing.
