Relevance in later versions of NODE

[tony-gutierrez]

I noticed that the benchmark script in this library really just compares keep-alive to non-keepalive.

Has any benchmarking been done against the normal http.Agent or https.Agent using keepalive and the same maxSockets?

Are there any performance benefits to using this library?

So, found an answer to my own question. Node doesn't do socket timeouts in many versions. I use 8.9.4 and it doesn't do it there (No timeout option: https://nodejs.org/docs/latest-v8.x/api/http.html#http_new_agent_options). Version 10 does seem to have a timeout option that it passes into the socket, but apparently this does not close the socket (https://nodejs.org/api/net.html#net_socket_settimeout_timeout_callback).

So using this library will indeed add that functionality to certain versions of Node.

agentkeepalive using the same code base as http.Agent.
You can find the different between these two agents: What's different from original http.Agent?

Node 8.9.4 have time option in agent constructor but no documented.

If the socket is timeout, will emit timeout event.
