Few SoCs whose clock speed is very less will cause multiple ticks to occur for 1 sec of sleep. For such a platform we cant run the loops for over 5000 because the tick handler will get executed. Thus rendering the test useless for such platforms. By reducing the number of iterations we get the required benchmark results.
