Hi Al,

first of all, I cannot reproduce the fact that drawers have such
a major influence on time, wit a test file that I created to
be similar to what you describe.

There is a way to speed up drawer handling, by using text properties
instead of overlays.  How have some vague plans to do this, but  
nothing concrete or soon.
