I have found Morphic to run more than adequately on very modest 
machines.  The problems may well be architectural or closely related 
to your VM.

>Squeak is dog-slow on my 440MHz SPARC (using Sunray terminals).

As I recall, the Sunrays rely on the network to display every pixel. 
While the Sunrays are truly wonderful in regards (particularly the 
capacity to copy images to plural terminals identified by smartcards. 
they may not be ideally suited for or matched to the particular 
manner with which your VM is redrawing the screen.  Does MVC work 
substantially better through the sunray?

>It's barely acceptable on my PII400 at home.  Still, even Swing is faster.

This is not my experience on my PC or Mac machines -- Swing being 
wholly unusable on all but the heftiest of my machines, and Morphic 
working quite well on all of them.  I haven't used any Unix Squeaks 
on a "full-time" basis anywhere, so I can't account for that here.
