How to make the Meteor consume less CPU and RAM

Use stream-server-uws

See also: meteor/meteor#10120

Introduction

By default, the Meteor Stream Server using the SockJS library for handling WebSocket messages of the Distributed Data Protocol (DDP).

The advantage of the SockJS library is that if the WebSocket protocol are not supported by a browser, then it allows you to use alternative transports.

The disadvantage it is eating CPU and RAM, and with a large number of DDP connections and messages, the memory starts to leak.

Can I use WebSockets only?

This solution based on the ClusterWS/cWS — C++ WebSocket implementation for Node.js.

How to use it now
