## Performance
By default promise-polyfill uses `setImmediate`, but falls back to `setTimeout` for executing asynchronously. If a browser does not support `setImmediate`, you may see performance issues.
Use a `setImmediate` polyfill to fix this issue. [setAsap](https://github.com/taylorhakes/setAsap) or [setImmediate](https://github.com/YuzuJS/setImmediate) work well.
