first of all, are you sure you're running without error-checking?
Yes. I'm comparing Debian's XEmacs 21.4.17 with Debian's GNU Emacs
21.4.1. I've known for a few years that Summary buffers exhibited
quadratic complexity, I just never imagined it could be really linear
under FSF.
it's also still possible it's the text property
implementation.

but maybe you're right about the textprops not being the
culprit;
the only way they could be inside of insert is through
`adjust_extents()' or friends ...
And those insertions are pretty normal -- I tracked them using an
"advice"-style logger. They simply insert stuff into the buffer, I
don't think there's even much jumping around.
