--------------------------------
This option optimizes the scheduler for common desktop workloads by automatically creating and populating task groups. This separation of workloads isolates aggressive CPU burners (like build jobs) from desktop applications. Task group autogeneration is currently based upon task session.
We do not need this for mostly server workloads, so just disable by default. If you need this feature really, just enable it by sysctl:
sysctl -w kernel.sched_autogroup_enabled=1
