Hard to keep a project under wraps and get an audience at the same
time, it is. I do realise it was inevitable LKML would invade my
personal space no matter how much I didn't want it to, but it would be
rude of me to not respond.

/me sees Ingo run off to find the right combination of hardware and
benchmark to prove his point.
[snip lots of bullshit meaningless benchmarks showing how great cfs is
and/or how bad bfs is, along with telling people they should use these
artificial benchmarks to determine how good it is, demonstrating yet
again why benchmarks fail the desktop]
I'm not interested in a long protracted discussion about this since
I'm too busy to live linux the way full time developers do, so I'll
keep it short, and perhaps you'll understand my intent better if the
FAQ wasn't clear enough.
Do you know what a normal desktop PC looks like? No, a more realistic
question based on what you chose to benchmark to prove your point
would be: Do you know what normal people actually do on them?
Feel free to treat the question as rhetorical.

his next H264 encode, changes music tracks and prepares to have his
arse whooped on quakelive.
