Dave actually explained this in the email you were replying to. By 
rendering directly to the screen the hardware can't help you. If you 
render to an off-screen buffer and then do an accelerated copy to the 
screen it will be much faster.

I tested Self 4.2 on a 600MHz G3 iBook and, as you wrote, the dragging 
is just as slow as before. So it wasn't a compiler issue. In fact, it 
is still slower than on a 600MHz Pentium II machine which doesn't have 
the SIC. And the Sparc, the slowest machine, beats them all. An 
interesting experiment would be to use X Window on the Mac and see if 
that makes any difference.
