[comp.sys.sun] Sparcstation Speed?

dak@super.org (Don A. Kreinbrink) (07/21/90)

Help!  I have a perplexing problem with a Sparcstation1.  The following
program runs in about 8.3 sec MOST of the time on my Sparc.  However, on a
frequent but intermittent basis it runs much, much slower (42 sec and up).
I have been unable to find any change in load avg, swaps, etc. to warrant
this big of a difference.  Does anyone have any ideas for me?

Sparcstation1  12Mbyte  SunOS 4.0.3

#include <stdio.h>
main()
{
       long i, j, k;
  
       for( i = 1; i <= 1000; i++ )
       {
             for(j = 1000; j>= 1; j--)
             {  
                    k = (i * i - 1) / j;
             }  
       }
}
