[RADIATOR] Issue with authentication and farmsize option

[Stefan Paetow (OpenSource)]

Hi Dubravko,

In the UK service, because we only have a limited number of processors
(with lscpu) on our new platform, we set our FarmSize to 3 times the lscpu
number, and it's certainly helped with throughput. So, I'd suggest setting
yours to 16, just to see how that improves the throughput?

Our old hardware actually had 12 and 16 processors (with 24 and 32 cores
respectively) and in those instances we literally got away with just
running the number of lscpu instances in the FarmSize.

Hope that helps.

Stefan
