NodeJS (just like Tomcat, Apache, etc) will probably do fine serving static files, while NGINX will give you much better performance since it was built in C and supports the sendfile system call which is as fast as you can get on a Linux OS.

See: blog.modulus.io/supercharge-your-nodejs-app..

The test I ran was 10,000 requests using 40 concurrent connections. Node.js averaged 862 requests/sec and Nginx averaged 1,608 requests/sec. This means Nginx can handle roughly double the throughput in my test environment.

Incorrect!

Node.JS is built in C, just like NGINX is. The difference is NGINX is static and can do pre-optimizations which wouldn't make sense for Node.JS to do. That being said, do use NGINX if you are expecting a large amount of traffic, it is much faster.
