Hello Robert -
I would be very interested to see what numbers you get with the new
ServerFarm parameter in Radiator 4.4.
Simply adding something like this to the configuration file (depending
on the number of cores available):
# ServerFarm to spawn multiple child processes
# NB: only supported on *NIX platforms
ServerFarm 5
Of course in typical production systems the bottlenecks occur
elsewhere - usually the backend database.
Many thanks for sharing this information.
regards
Hugh
