Returns an array of objects containing information about each CPU/core installed:
model, speed (in MHz), and times (an object containing the number of milliseconds the
CPU/core spent in: user, nice, sys, idle, and irq).

See the [node.js documentation](https://nodejs.org/api/os.html#os_os_cpus) for
`os.cpus()`.

In the browser, the `navigator.hardwareConcurrency` API is used, when available.

## install

```bash
npm install cpus
```

## usage

var cpus = require('cpus')
console.log(cpus().length) // 4
```
