CONTENTS

 This  package  contains  the  well known 'Dhrystone' benchmark.  It's
available  everwhere  on  the  net  - but if you wish to compile it on
AMIGA,  you  need  to  alter  the  source a little bit.  The source is
adapted  to  take  advantage  of the 'timer.device' - NOTHING else has
been altered.


WHAT'S NEW

 I  discovered  even  more optimization-switches at the compiler - now
the executables are around 15% faster on my machine.
Release date: 05-Jul-1995


USAGE
 Just  run  your  favourite  version  (1.0,  1.1  or  2.1)  from  your
'processors  directory'  (68000+,  68020+, 68040+).  For each CPU, the
benchmark  runs  at  a  useful  (IMHO) loop count.  The excutables are
compiled under SAS/C 6.55.


INFO

 I  wished  to  have  the  standard  dhrystone  around - just from the
original  sources  and optimized for my processor.  So I could compare
our  workstations and a some PC's (under LINUX) to my A4000/040.  Here
are the results from DHRYSTONE 1.1:

DEC ALPHA AXP        150MHz   427000   CC (GNU/C rates 377000, only)

A4000/60/Cyberstorm   60MHZ    90000   SAS/C

Notice,  that  I NEVER compiled the benchmark 'register-optimized',
because   this   benchmark   should   rate   the   speed   of   the
processor-memory interface (while performing lots of 'string-copy')
and not the capability of the CPU (especially at RISC-design) to
store runtime variables at dozens of registers.
