I'm on the job. :)

I'll write back with an official report. Suffice it to say that my early
experiments show org-mode cruising through the examples you gave me, but
slowing considerably whenever, as you suspected, there are numerous
nested overlays.

I tried, unwisely, to create a tree consisting of 100 subtrees, each of
which contained a quote, a drawer, and 100 additional subtrees, each of
which, in turn contained a drawer. It not only took the better part of a
minute to cycle the tree, but it sent my emacs memory usage
skyrocketing. Needless to say, 10000 nested entries, each with quotes
and drawers, is an extreme case. :)

Best,
Matt
