Poor Sun timings, as competition...

   The Compile System took about 14 minutes.  Compiling and loading it on a
   Sun 4/280 running Sun Common Lisp 3.0.1 takes about 4 CPU minutes with
   the developmentc compiler and 16 CPU minutes with the production
   compiler (wall times were about 5.5 minutes and 19 minutes).  And on the
   3630 at SLUG it took over 40 minutes.  So, if you're in a heavy
   edit-compile-run cycle the Sun wins.

Excuse me, but aren't you still ending up with a comparison of
Symbolics' obsolete model (3630) with Sun4s?  I think you intended
this message to compare the Symbolics XL1200 with the Sun4.  

Also, if you are most interested in "a heavy edit-compile-run cycle",
then perhaps you could comment on how well the Sun development
environment supports a programmer spoiled by Genera.  My opinion is
that the Suns are quite usable, but still have a long way to go to be
in the same league as Genera.
