The 3100-38 was the first 3100 model made. I can't imagine anything on 
that machine would compare favorably against anything on any Alpha...
VNC under VMS? Might be issues with the implementation of that on the 
Alpha, issues with you you configured things, as well as network and god 
knows what else.
Also, I guess this implies X11, so how did your local machine talk to 
the graphics subsystem? Local or using the network? That can make a big 
difference as well.
