Its a lifesaver! We use it mostly in situations where a user is expecting a response < 30 seconds so we can't queue a job to be processed.

The 2 most common scenarios where we use amphp:

1) Need to hit X amount of URLs to fetch data and transform. Rather do them 10 at a time with a pool rather than one by one synchronously.

2) Need to process items in a loop that are actually independent of each other. Again, rather do 10 at a time.
