title: Is there a limit for concurrent requests for one axios instance?
body: <p>So I am a creating an axios instance that connects to some API like this:</p>
  <p><code>const instance = axios.create(...)</code></p>
  <p>I want to know is there a limit to how many concurrent/parallel requests axios would be able to make with that singular instance. Reason for this is because I have a back-end app that receives hundreds of requests a minute and that number will only keep going up so I want to understand how the axios instance behaves under the hood to know if there is anything I need to do to avoid some sort of overload and requests getting dropped, delayed, and/or unfulfilled.</p>
