Easy to say, but I can't file a _useful_ bug report because I don't
know where the latency comes from, most of the time (font-lock-mode is
an extreme case; there's also something fishy with mule, or at least
japanese input/display, but I still haven't been able to identify
whether that's even xemacs at fault). I'd have to either spend about a
week dissecting all the elisp on my system until the problems stopped,
or learn enough about elisp in order to profile the damn thing
properly. I don't really have time or inclination for either.
I'm pretty sure I'm looking at a handful of bugs - but the nature of
emacs makes them difficult to even report, let alone locate and fix.

Yup. Not a coincidence >:)
It's a good example of why performance is still a problem, and
probably always will be, regardless of how fast systems get. Sure, in
theory it could be fixed without making any huge changes, but in
reality it *isn't* fixed. There are various reasons for this, and I
find they're usually much more significant than the "underlying
architecture", in any program.
Or, more succinctly: what use is there in worrying about the
architecture if it can't solve the real-world problems?
