The slowness stems from the fact that your machine
is more than 2 years old, or something like that,
isn't it ?

For solving this problem, we really need to
profile TeXmacs much more than in the past,
and do the tests on an old machine. That's
what I plan to do, at some point.

This "filter" idea is a quite good one, and it should not
be very difficult to implement. I will think about that.
