Speed measurement

fork
This is a fork of ThaUnknown/throughput.
install
npm i -S @substrate-system/throughputUsage
Import as normal.
import { throughput } from '@substrate-system/throughput'
import fs from 'node: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) // use a 20s buffer insteadThis is an improved version of speedometer by @mafintosh, which used timeouts, which cause a lot of issues.
