I'm curious if I could gain any advantage if I'll serve static HTML files using Node.js instead of Nginx. I know Nginx is written in C but does it serve files in a non-blocking fashion? I though Node.js can server more files(support more requests pe second) because I can write non-blocking code.
Both Node.js and Nginx are asynchronous (non-blocking) servers. Nginx is definitely more well suited for serving your static files. However, depending on your use case, the difference may not be worth the added administration overhead. You would really have to be running a significant amount of traffic before you would notice the difference.
