What usage pattern are you designing for? The most common pattern I've
seen is for short intermixed operations on a connected set of buffers. So
just what is the average length of the concurrent batch buffers (with
correct inter-ring flushing) versus a much simpler modal approach?
And do you have any x11perf figures yet?
