Problem

A project is projected to be storing more than 10 billion data by next year. Measuring how intensive processing these data might give one a good picture of how they should prep.

Planning

The algorithm used to measure interval consists of two data point: the start time and the end time, measured before and after a function’s execution.

The interval is thus end - start

Time in JavaScript can be measured using the Date object.

Product

var start = new Date().getTime();

//Any kind of function is here
for (i = 0; i < 10000000000; ++i) {}

var end = new Date().getTime();
var time = end - start;
console.log('Execution time: ' + time);
