Answer 1

One of the reasons you see this is because you make the calls in "parallel" . You do start the calls one after the other , but the loops will end probably before the first results returned from the server. The loop continues until the end , making the call stack filled with 1000 async requests to the server .

Your'e are hitting hardware/software limits and nothing is wrong with the code. if you did want to build a server which can handle 1k (and much more) requests concurrently I would take a look into the "cluster" module of node .

Please notice that when doing network job between server , it's acceptable to use a concurrency limit . (for example: up to 4 requests concurrently)

but you can always scale your server beyond one machine and handle much more traffic .
