Message-ID: <CANQmPXjXt4KsYix5syDrRo_qt3DD7tMtHpdNa3Sh-fWhi53Lnw@mail.gmail.com> Date: Sun, 8 Jul 2012 11:37:45 +0800 From: Chen <hi3766691@...il.com> To: Oleksandr Natalenko <pfactum@...il.com> Cc: linux-kernel@...r.kernel.org Subject: Re: [PATCH]RIFS-V3-Test For 3.4.x kernel. I haven't made any support for Cgroup yet. After I finished translating the scheduler in modular form it will support Cgroup naturally since the modular scheduler support Cgroup. Anyway it is for desktop users and I don't think I have to support Cgroup in short term. I am going to post the graphical benchmark between RIFS-V3-Test and CFS. On my box, The latency of CFS is 8 times of RIFS averagely.However I am not using my computer right now so I can't post my benchmark now.
