API

• loopbench()

• 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 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 becomes true, and the load event is emitted.

---

instance.overLimit

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

---

instance.stop()

Stops the sampling.
