A minimal overhead event loop delay sampler.

Polyfill for perf_hooks.monitorEventLoopDelay(...)

Small module to do smart delays in tight loops to maintain a certain event loop delay

Memory and event loop testing for Node.js — heap monitoring, event loop delay and utilization tracking, object lifecycle verification, stream buffer assertions, and comparative profiling

get nodejs performance, such as: heap statistics, event loop delay

Check the event loop delay

Timer-lateness measure for @ac-bench: reports drift, overruns and tail lateness from perf_hooks event-loop delay monitoring.

Event Loop Monitor for Node.js to track event loop delay and utilization (framework agnostic)

A shim for the setImmediate efficient script yielding API

An efficient queue capable of managing thousands of concurrent animations.
