The cPnginx is a cPanel nginx integration plugin. This plugin will increase your server performance and decrease server loads caused by apache web server. Nginx+cPanel+Apache= Performance boosted secured hosting server. Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption. Unlike traditional servers, Nginx doesn't rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but more importantly, predictable amounts of memory under load. Even if you don't expect to handle thousands of simultaneous requests, you can still benefit from Nginx's high-performance and small memory footprint. Nginx scales in all directions: from the smallest VPS all the way up to clusters of servers. Nginx powers several high-visibility sites, such as WordPress,Hulu, Github, Ohloh, SourceForge and TorrentReactor.
