I have not seen this fix in action, (above is just one line from
the original posting).
But in my *experience*, the updating is carried out in very
unoptimal way, a process which I describe as shunting. It really does
not have a lot to do with the overhaed.
If you do
  set term=vt100
  setenv TERM vt100
  unsetenv TERMCAP
etc, (ie pretend the screen is a vt100) the process of scrolling
speeds up. Of course, other features like the status line, get
messed up.

Moral. SUN's termcap entry for `sun' is wrong.
