Double-buffering would have a smoother appearance than what
you're doing, but it would not be faster.
Look at what MemoPad does*. Instead of redrawing the entire
screen, it does a window-copy of most of the screen to make room for
the new text, and then writes the new line. It requires some
bookkeeping, but it is a lot faster. I successfully borrowed the idea
(and quite a bit of code structure) to do the same thing in one of my
applications.
* Having good example code is wonderful. I don't know if I can say
that enough times.
