However, I haven't seen definitive tests on scaling that far. Last I saw, somewhere in the 6 to 8 core range, you really hit the point of diminishing returns. If you are doing lots of jails, I would suggest splitting up 'sets' of jails and limiting them to run on a group of specific cores. In the above configuration, you could have 8 groups of 8 cpu-cores, each handling a specific set of jails. Good luck
