# loopbench

Benchmark your event loop, extracted from [hapi](http://npm.im/hapi),

[hoek](http://npm.im/hoek), [heavy](http://npm.im/heavy) and

[boom](http://npm.im/boom).

## Install

To install loopbench, simply use npm:

```

npm i loopbench --save

```



## Example

See [example.js][example].



## API

  * loopbench()

  * instance.delay

  * instance.limit

  * instance.overLimit

  * instance.stop()

-------------------------------------------------------



### loopbench([opts])

Creates a new instance of loopbench.

Options:

* `sampleInterval`: the interval at which the eventLoop should be

  sampled, defaults to `5`.

* `limit`: the maximum amount of delay that is tollerated before

  [`overLimit`](#overLimit) becomes true, and the `load` event is

  emitted, defaults to `42`.

Events:

* `load`, emitted when `instance.delay > instance.limit`

* `unload`, emitted when `overLimit` goes from `true` and `false`

-------------------------------------------------------



### instance.delay

The delay in milliseconds (and fractions) from the expected run.

It might be negative (in older nodes).

-------------------------------------------------------



### instance.limit

The maximum amount of delay that is tollerated before

[`overLimit`](#overlimit) becomes true, and the `load` event is

emitted.

-------------------------------------------------------



### instance.overLimit

Is `true` if the `instance.delay > instance.limit`.

-------------------------------------------------------



### instance.stop()

Stops the sampling.
