I just tried this.  Under V.3 on a 16Mhz 386 ( Intel production board,
with a 387, which shouldn't matter ), I get 12.6 real, 11.2 user, .6
system.  bc was compiled with rcc.  There were other users on the
system, but they weren't doing anything significant.

It appears to me that the 386 and the 68020 are about the same.  To
an end user, does it really matter which is in the box? 

Just for fun, I tried this on an AT&T 6300+ running V.3 in 1 meg of
ram.  The results were 46.1 real, 40.3 user, 3.6 sys.  If anyone
wants to give me a cray, I will try it there too. :-)
