I didn't find a visual that address that specifically; although the spice for newbies does have a lot of information which I haven't fully digested yet. I do think I have the beginning of a thread to understand the specific bug I'm seeing. I see on the client that I get 500 or so draw fill operations each time I move the mouse over a menu choice. If we require an ack every 20, at a WAN price of 80 ms per ack, you very rapidly go right down the tubes. So figuring out why those draw fill operations didn't get condensed seems like the right place to start. Am I on the right track in looking at red_current_add in red_worker.c? And it looks like turning on PIPE_DEBUG may well get me a whole lot more info - I'll start with that. Any other tips or clues are appreciated.
