No definitive answer from me.
But a guess: ISTR seeing that the Plan9 kernel 'lacked a scheduler'.
That can be inconsequential for some situations, very important for others.
That may be stale or even just plain wrong info.
In any case, I'd like to know more myself about the relative effectivness of the
'native' Plan9 & its kernel vs other 'real', not 'virtual' OS'en.
Being able to 'plumb' and network inherently 'better' is not all that useful if
a less-elegant OS does better with the BFBI API set.
Any benchmarks (yeah they lie, but ....) around?
Bill
