Beginning with this launch, Node.js units keepAlive to true by default. Because of this any outgoing HTTP(s) connection will routinely use HTTP 1.1 Maintain-Alive.
The default keep-alive period is 5 seconds.
Allow keep-alive will ship higher throughput as connections are reused by default.
Moreover, the agent is now in a position to parse the response Maintain-Alive which the servers would possibly ship. This header instructs the shopper on how a lot to remain linked.
On the opposite facet, the Node.js HTTP server will now routinely disconnect idle shoppers (that are utilizing HTTP Maintain-Alive to reuse the connection) when shut() is invoked).
Node.js HTTP(S)/1.1 requests might expertise a greater throughput/efficiency by default.
