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.
