The cgroups framework is simply a way of grouping processes together
and allowing subsystems (memory, CPU, disk I/O, etc) to associate
state objects with each group. Generally this is for improving
isolation rather than improving performance - sticking extra machinery
and scheduling in will typically reduce overall throughput, but make
it more practical to share resources safely between multiple groups of
processes.
Your question is pretty open-ended - what's your ultimate goal? You
should probably be focusing on some particular problem that you're
trying to measure/improve via resource isolation/scheduling.
