0W-httpd can be used for sites with static content, special purpose sites like banner servers, high-loaded general sites (as reverse proxy).

Features:

• single process model;
• low memory and CPU consumption;
• fast responses (up to several thousands requests per second);
• large number of simultaneous connections (up to several thousands);
• acting as reverse proxy for general purpose servers (like Apache);
• http-enhancements: keep-alive, pipelined requests, byte-ranges (resuming);
• modern mechanisms of Linux (epoll, realtime signals, sendfile) and FreeBSD (kqueue, sendfile).

OSes: Linux, FreeBSD
Current version: 0.8d

Note: 0W-httpd is created for internal usage, it has no public support, it's documented poorly (and mostly in russian, sorry).
