In the longer run, we should aim to make Emacs fast enough even in those modes. I can't promise anything, but if you can provide sample files and steps to trigger the slow behavior, maybe someone will be able to find the culprit as well as a fix/workaround. Of course, it is quite likely that the slowdown is due to a combination of things, so "the fix" is a long and painful one, so it might be difficult to find someone motivated enough. Stefan
