Nginx Overview

Nginx is a lightweight web server which also acts as a reverse proxy server and email (IMAP/POP3) proxy server. It features low memory usage and strong concurrency capability. Nginx supports FastCGI, SSL, virtual hosts, URL rewrite, Gzip, and extension of many third-party modules.

The Nginx performance varies depending on the hardware, operating system (OS), and software in use. It is also affected by the design of each subsystem, algorithms used, and compiler settings.
