Sparcstation Speed?

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;
}
}
}
