Node.js is single-threaded and uses non-blocking I/O, allowing it to scale and support tens of thousands of concurrent operations.

It shares these architectural characteristics with NGINX and solves the C10K problem – supporting more than 10,000 concurrent connections – that NGINX was also invented to solve. Node.js is well-known for high performance and developer productivity.

To get the most out of Node.js, you need to cache static content, to proxy and load balance among multiple application servers, and to manage port contention between clients, Node.js, and helpers, such as servers running Socket.IO. NGINX can be used for all of these purposes, making it a great tool for Node.js performance tuning.
