Byte Benchmarks results

[Shawn Hayes]

     Since everyone is interested in comparing the RS 6000 family to the other
families of machines that are available here is my contribution to muddy the
waters.  The following numbers are the results of the Byte Unix Benchmark suite
running on the 8943Q release of AIX 3.0 using a RS 6000/320.  These results
are very close to what I got using the 9005 release so I don't expect much
change in the release version of AIX.

A couple of points about the above benchmarks

1) the Everex machine is an Everex 33 MHz 386 running SCO Xenix 366 V2.3.1 with
   4 meg and a 80387 math co-processor
2)  The dhrystone test for the RS 320 is based on a HZ of 100
3)  The dhrystone test for the HP 360 is based on a HZ of 60
4)  The dc test(which test the calculator) didn't work on version 8943Q of
    AIX 3.0.  I don't have my results with me, but I recall the results of
    the dc test with the 9005 version being approx. 0.50 secs.  This number
    is very likely wrong since I'm very hazy on the exact number.
    


In addition BYTE rates the machines based on the results of a few of the      
benchmarks when comparing the computers against the Everex 386.  The benchmarks
are   dhry2,   float,   shell8,   cc,   dc   and  tower.  The results for
each of the computers are:
Everex      6.00
NeXT        3.54
DEC 3100   11.12
HP 370      5.37
HP 360      4.10
RS 320     14.59    (note this is without the dc test times)



In addition there are other tests that measure file-system throughput and other
items that a potential buyer might want to know.  If there is enough interest
I can post the entire results.

PS:  I have a letter stored off where someone offered to put the benchmark 
source up for FTP if I sent it to him.  I should be sending it out sometime
in the next couple of days so it will be available this week for anyone else
who wants to test the IBM machine or any others.
