I can put up without the >> fontification so this is what I am doing now. It's true that setting `org-src-fontify-natively' to nil boosts performance but it's only half the story. Editing something inside blocks also has a significant negative influence on display performance. Removing things like `#+BEGIN_letter' / `#+END_letter' from the file gets things back to normal for me. Ulf
