If we're going to redo the interactivity estimator I happen to have a whole cpu scheduler design that is interactive by design without being a state machine that I've been hacking / maintining / debugging for 2 years that many people are already using in production...


What do you mean interactive by design (presumably as opposed
to the current scheduler which is not interactive by design)?

And what do you mean by not being a state machine?

Back on topic: I don't think that this patch isn't clearly
better than what currently exists, nor would require less
testing than any other large scale changes to the scheduler
behaviour.

So, as Con seems to imply, it is JASW (just another scheduler
rewrite). Not that there's anything wrong with that... except
it is not really a good fix for a problem with the current
scheduler.

Thanks,
Nick
