Node global agent defaults to infinite number of max sockets, which will probably be too many if you have very high traffic on your post endpoint. I am not sure of the nuances of the maxSockets, (do requests block if a socket is available, how are sockets reused? How does keep alive work? etc).Ģ0 is arbitrary and your apps number will probably require fiddling with to see what works best. This should allow you to have a pool of 20 sockets.
