While it's true ISC's Hercules server probably hasn't gotten the
attention the VGA server has, I doubt it could be made too much faster.
There were some improvements made to text output since the 1.0 release,
but scrolling won't change much.  The basic problem here is that we're
dealing with a slow 8 bit DRAM device running over a slow bus.  I have 
heard that on a VGA with a 16 Mhz 386, you're stuck with 20 or more
wait states.  I've found that accessing video memory can take more than
6 times as long as accessing normal memory.  Welcome to the wonderful
world of the IBM PC.
