Charles Allen commented on MESOS-314:
-------------------------------------

Druid.io is having big-node scaling issues reported by the community (see https://groups.google.com/d/msg/druid-user/l5grbWf2x9w/nF5fPyiaBQAJ ) I think having proper cpuset / memory controller isolation per task would help with this tremendously.

> We'd like to add support for the cpusets subsystem, in order to support pinning to cpus.
> This has several potential benefits:
> 1. Improved isolation against other tenants, when given exclusive access to cores.
> 2. Improved performance, if pinned to several cores with good locality in the CPU topology.
> 3. An alternative / complement to CFS for applying an upper limit on CPU usage.
