====== C10K ======

===== C10k problem =====

The C10k problem is a limitation that most web servers currently have, which limits the web server to being able to handle a maximum of about ten thousand simultaneous connections. This limitation is due to a combination of operating system constraints and web server software limitations.

A few web servers have been developed to counter the C10K problem:
  * nginx, which relies on an event-driven (asynchronous) architecture, instead of threads, to handle requests (WordPress.com uses nginx to solve the C10K problem)
  * Lighttpd, which relies on an asynchronous architecture to handle requests
  * Cherokee, a lightweight web server
  * Tornado, a non-blocking web server and web application framework
  * Deft, asynchronous, non-blocking web server running on the JVM
  * Node.js, asynchronous, non-blocking web server running on Google's V8 JavaScript engine
