Are you still seeing this behavior?  I tried to reproduce it to see if
anything has changed or if some of new Vim changes had helped, but
didn't see any noticeable performance problems.

I bisected back to the patch that introduced the general slowness in
syntax-based folding and didn't notice the behavior you describe in any
of the steps along the way.  Either I'm not following the directions you
provided properly or the folding computation isn't the dominating factor
on my computer.
