But, are any of these benchmarks really engaging the 4BSD/ULE scheduler =
differences? Most such benchmarks are run on a system with no other load =
whatsoever and in no way represent real world experience.

What is more, I believe in such benchmarks "the system feels sluggish" =
is not measured at all. Even if it is measured, if in such case the =
benchmark finishes "better" - that is, faster, or say, makes the system =
freeze for the user for the duration of the test -- it will be =
considered "win", because the benchmark suite ran faster on that =
particular system -- whereas a system which ran the benchmark fast, =
provided good interactive response etc would be considered "loser".

I think it is not good idea to hijack this thread, but instead focusing =
on the other SCHED_ULE bashing thread to define an reasonable benchmark =
or a set of benchmarks rather -- so that many would run it and provide =
feedback.
