Even if you shrink the window so that only Latin characters are
visible?

I sincerely doubt that.  This box is 5 years old, it cannot be too
fast by today's standards.

OK, will do later.  As a first approximation, try this:

  emacs -Q -fn "Arial Unicode MS"

This will make that font the default font, and Emacs should also use
it for most/all the funny characters that are supported by Arial.  I'd
be interested to know if this is still slow.
