This will make the CFS in Linux kernels be happy (as marking too many threads as critical actually reduces performance). The load balancing gets distributed evenly across the 4 cores which will outperform in a 8-core setup system. We still have over 40 threads but this SHOULD help to reduce thread contention (especially since the CPU thread is one of the most important to run). The scheduling should be ideally left to the OS as most of them have decades of running proficient scheduling algorithms which likely outperforms any hand-made solutions.

This will make the CFS in Linux kernels be happy (as marking too many threads as critical actually reduces performance). The load balancing gets distributed evenly across the 4 cores which will outperform in a 8-core setup system. We still have over 40 threads but this *SHOULD* help to reduce thread contention (especially since the CPU thread is one of the most important to run).
