throughput
Speed measurement
npm install throughput
Usage
const throughput = require('throughput')
const fs = require('fs')
// Let's measure how fast we can read from /dev/urandom
const speed = throughput()
const stream = fs.createReadStream('/dev/urandom')
stream.on('data', function(data) {
// Simply call speed with the amount of bytes transferred
const bytesPerSecond = speed(data.length)
console.log(bytesPerSecond+' bytes/second')
})You can always get the current speed by calling speed().
Per default throughput uses a 5 second buffer.
To change this simply pass another value to the constructor
const speed = throughput(20) // uses a 20s buffer insteadThis is an improved version of speedometer by mafintosh, which used timeouts, which cause a lot of issues.
