Test CPU Speed using JavaScript

Run this code above and see how fast your processor does the math.

var startTime = new Date();
document.write(“Thinking …..”);
var i = 0, j=0;k = 0, sum = 0;
for (i = 0; i <= 1000; i++)
for (j = 0; j < 500; j++)
for (k=0;k<500;k++) {
sum = i + j + k;
}

var endTime = new Date();

var diff = endTime – startTime;
document.write("
Done “);
document.write(diff + ” milli seconds passed”);
