How to Measure Execution Time in Node.js

execution-time.js

var start = new Date();
var hrstart = process.hrtime();

setTimeout(function (argument) {
    // execution time simulated with setTimeout function
    var end = new Date() - start,
        hrend = process.hrtime(hrstart);

    console.info("Execution time: %dms", end);
    console.info("Execution time (hr): %ds %dms", hrend[0], hrend[1]/1000000);
}, 1);

// Execution time: 1ms
// Execution time (hr): 0s 1.025075ms

Thank you, very useful!
