Why NGINX is faster than Apache?

But nginx does not require context switching, since a single thread can serve all requests (actually we typically configure nginx to run in as many processes as there are CPU cores). This is the main reason why nginx is faster, meaning it can serve more requests per second than Apache on the same hardware.

NGINX is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more . It started out as a web server designed for maximum performance and stability.

NGINX is a free, open-source, high-performance HTTP server and reverse proxy , as well as an IMAP/POP3 proxy server.

NGINX performs 2.5 times faster than Apache according to a benchmark test performed by running up to 1,000 simultaneous connections. Another benchmark running with 512 simultaneous connections, showed that NGINX is about twice as fast and consumed less memory.
