I can confirm this makes a *huge* difference. I'm running sup on a
pretty big machine, but at times it's so creeping slow I'm considering
moving back to mutt.

Using the parameters you suggested speeds up things considerably,
loading big threads is now fast enough to be usable without getting
annoyed.                                                               

Thank your *very* much for pointing this out. I hope Sup will pick this
up and integrate it in the default application in some way.
