speedometer
Speed measurement in Javascript
npm install speedometer
Usage
var speedometer = require('speedometer')
var fs = require('fs')
// Let's measure how fast we can read from /dev/urandom
var speed = speedometer()
var stream = fs.createReadStream('/dev/urandom')
stream.on('data', function(data) {
// Simply call speed with the amount of bytes transferred
var bytesPerSecond = speed(data.length)
console.log(bytesPerSecond+' bytes/second')
})
You can always get the current speed by calling speed().
Per default speedometer uses a 5 second buffer.
To change this simply pass another value to the constructor
var speed = speedometer(20) // uses a 20s buffer instead
