[RADIATOR] Use FarmSize parameter

[António Mendes]

Hi Hugh, thanks for your answer.

The "father" process is consuming too much CPU due to the amount of 
requests, it's perfectly normal because we have a huge amount of 
clients. The Radiator's performance it's not a problem.
We need to move forward because we see that the hardware it's 
underused(one CPU core reaches several time 100% of use but the others 
are unused).  To avoid this problem and make use of all cores available 
we take a look of "Farmsize" feature, but like I said we are a bit 
worried about problems that could arise, like concurrency problems. So 
my question is if there are known problems in use the Farmsize, or do 
you advise to upgrade the configuration in another way.

Please note that we are thinking to use the Farmsize in accounting 
process, so the known authentication problems will not be a problem for us.

Best regards,

António Mendes
