Which machine was running at 83%, he VAX or the Windoze box?  What are you
running on the VAX?  VMS?  Ultrix?

Both Ultrix and VMS would require tuning to run DECwindows well - 
especially VMS.

I have run DECwindows on a VAX 3100 model 300 under VAX/VMS 5.5-1 using the 
Motif window manager with a dozen remote DECterms open plus Emacs, a clock, 
a calendar, etc. and it gave reasonable performance.  The VAX was both the
X client and the X server except for the remote DECterms that I used to
manage a wide assortment of VMS and Unix machines.

I was able to run Mozilla on it but performance was horrible so I tried a
browser remotely on a Alpha running Digital Unix but that was long ago
and ISTR that the browser crashed because it did not like the monochrome
display on the VAX - that seems wierd.
