Note that this is for improving fairness between applications, not total
throughput of the machine. It will gain you nothing if you run a single
server; what it gains you is that you can take your low-priority batch job
and run it next to your mission-critical web server, without having to worry
it will eat up all your L3.
Needless to say, it is for advanced users.
