    If you have older Emacs 24.x installations somewhere, can you try the
    same with those?  I don't think something's changed significantly in
    this area since Emacs 24.1, where bidirectional display slowed such
    long lines some more.

I should explain that I configured Emacs to visit that file in Rmail mode.
Try it that way.

I tried visiting it in 24.3.50.1 from May 1 2013.
Scrolling the file in Rmail mode is much faster in that version
than in the current version.  So is C-n.

With find-file-literally it is almost instantaneous
in both 24.3.50.1 and the current version.
