I agree. I have seen really fabulous system response since Rik's
changes were merged in.
I have managed to crash my machine a couple of times (I am working on
getting a
serial debugging connection set up, since I don't see any OOPS
messages), but I think this
is not terribly surprising. My impression is that system responsiveness
is much improved.
Let's hang in there a bit longer. We are making rapid progress on
testing and fixing.
