    fail!

    BFS is about latency, not throughput!

    this benchmarks are totally inadequate. BFS scheduler is designed to reduce LATENCY in desktop applications.

    i'd check for amount of frames dropped in some FPS game or quality of video capture framerate-wise, as this is where the scheduler latency matters. but these things cannot really be measured with a benchmark ( i think ).

    before CFS epsxe emulator would stall randomly for ~0.5 second now and then. on CFS i sometimes get 0.1 sec delays, which is not the case with BFS at all. that is what should be measured, not performance of webserver or how much FPS can you squeeze of a game.

    Phoronix staff - please, read again this post http://lkml.org/lkml/2009/9/6/231 and think about this article again.

    Phoronix: Two Years With Linux BFS, The Brain Fuck Scheduler

    This month marks the two-year anniversary of the release of BFS, the Brain Fuck Scheduler, for the Linux kernel. While BFS has not been merged into the mainline Linux kernel, the scheduler is still actively maintained by Con Kolivas and patches are updated for new kernel releases. The BFS scheduler has also reached mild success and adoption over the past two years. In this article is a fresh look at the Brain Fuck Scheduler along with a fresh round of benchmarks from the Linux 3.0 kernel.
