as long as you don't ask any money for it, except perhaps a nominal
fee for copying.


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.


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 486/DX33 (under LINUX) to my A4000/040.  Here
are the results from Dhrystone 1.1:


Machine:       Clock:   Result:  Compiler:
---------------------------------------------------------------------
DEC ALPHA AXP (150MHz): 427000   CC (GNU/C rates 377000, only)
SUN SPARC 10  ( 33MHz):  83000   GNU/C
PC 486/DX33   ( 33MHz):  28000   GNU/C
A4000/40      ( 30MHz):  38000   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.


GREETINGS

 to Steffi, Jerome, Mark, Stefan, Michael, Thomas, as usual..
