It's a little hard to tell the order of events given that things

window is updated. It's that last item that seems significant: the
entire window is updated with each keystroke.
Bennett,
the attached should produce a noticable speedup.
(Lars likes simple patches :)
Well, I'm comparing apples and oranges a bit, but I'm not noticing
much of a speed-up.
I've applied your patch to the version of lyx I compile with gcc-4.0
(because the gcc-3.3 version I'm currently using for profiling).
Comparing that against a stable gcc-3.3-compiled version (without
profiling info and otherwise configured identically), I don't notice
any difference just by typing.
Being a bit more systematic: When I type a sentence into a long
paragraph -- the same conditions under which it took me 8 seconds to
type and lyx (gcc-3.3) 16-17 seconds to display -- it takes 15
seconds to display with the patched version. I've done it several
times with reasonably reliable results, so I think it is fair to say
there is a minor speed-up.
Using Quartz Debug to look at window refreshes, I don't notice any
difference.
Finally, I applied the patch to the version of lyx compiled with
gcc-3.3 with profiling info, ran Shark (in the same way I did
before), and placed the report here: <http://edisk.fandm.edu/
bennett.helm/LyX/shark-profile-2.txt.zip>.
