i have been dealing with latency also, often in undo-tree. this might
be a dumb suggestion, but is it related to org file size? my files
have not really grown /that/ much but maybe you could bisect one. as
opposed to config.
i am not saying that your org files are too big. just that maybe it
could lead to insights.
