Gee, how fast do you want it...try the following two things:

1. in .defaults (or create a ~/.defaults) add the line

	/Tty/Retained "YES"

this does a speed/memory trade-off and seems to speed update up
quite a bit. I forget if you have to re-boot or just start a new
shelltool to make it take effect, whatever.

2. Make a termcap entry for sun that removes al and dl capabilities,
you may find that seems faster, especially with the first change.

This is all within sunwindows, on the raw console things may be different.
I dunno, *mine* updates the screen instantaneously it seems. Maybe I'm slow.
