John (and anyone else who is interested)

Here are the 386 numbers

Benchmark Environment
The results were obtained with the Green Hill's FORTRAN compiler 
version 1.8.2G.  The system we used to run was an Intel Multibus I system 
running Unix System V Release 3.0.  The CPU board was a 386/24 
MultiBus I which has a 64 Kbyte direct-mapped write-through
cache and 2-3 wait states for cache misses.

The floating point processors were the Intel 80387-16 and -20 MHz
and the Weitek 1167 chip set (also at 16 and 20 MHz)


Benchmark	16 MHz			20 MHz		
		387  	1167		387	1167
Whetstone (FORTRAN 77)
 Single		1510K   3310K		1860K   4170K
 Double         1380K   2070K		1730K	2590K

Linpack (FORTRAN)
  Rolled Single  182K	494K		225K	662K
  Rolled Double	 151K	306K		187K	383K
Unrolled Single  193K	541K		238K	669K
Unrolled Double  158K   323K		195K	405K

There is still some room for improvements in the compiler but these
numbers should be fairly representative of the performance of our
processors.  The version of the compiler which generated these numbers
is stil very new (less than two weeks) so there is the possibility
that you may have recieved out of date results.
