Hi folks,

I think you are on the wrong line. Back in 1986/87 I wrote Terminal DA
which works on a Mac+ at 9600 baud, while not scrolling. It uses
DrawText of as many characters as possible.

You must be doing something else wrong. Look at your source or do some
performance meassurements.

Somebody else already pointed out that you aren't granted that your GrafPort
is frontmost. Also, you had to test yourself if all of your Port is on screen
(or will your users not allowed to drag the window?).

Btw,  I tried very much the same you did back in 1986. I got a speed improvement
of only 40% (using a font 8 pixels wide and a byte aligned grafport). Look
elsewhere for big improvements...
