不使用等待异步的性能问题 function

Question

I'm using nodejs for one of my server applications. But I found out there's some latency while running my app and I found that I didn't use await for a async function. Is there any performance issues while not using await for a async function?

Answer 1

The async-await is used to simplify the complexities created by nested callbacks. So, both async-await and callback patterns serialize asynchronous processes.

This means that one process fires after the completion of another and, this could be experienced as a latency depending on the application.

So, NO - async-await does not create any latency in its own right.
