SPServer is a high concurrency C++ server framework library that implements the Half-Sync/Half-Async and the Leader/Follower thread pool patterns. It is based on libevent (Unix/Linux) and IOCP (Win32) in order to utilize the best I/O loop on any platform. It supports SSL for secure transactions. An SSL proxy, sptunnel, is included along with an embedded HTTP server framework, sphttp.
muhttpd (mu HTTP deamon) is a simple but complete Web server written in portable ANSI C. It supports static pages, CGI scripts, and MIME type based handlers. It drops privileges before accepting any connections, and can log received requests. It has been tested on OpenBSD, GNU/Linux, NetBSD, FreeBSD, Mac OS X, and Cygwin. It runs successfully on 32-bits, 64-bit, little endian, and big endian systems.
PasTmon (Passive Application Response Time Monitor) passively monitors your application servers, measuring and reporting user response times, throughput and congestion. It currently works with HTTP, telnet, rlogin, rsh, FTP (control channel), SMTP, POP3, and IRC. Measurements are recorded in a PostgreSQL database and are presented graphically via a PHP Web front-end using R statistical analysis scripts to create the plots.
mod_cband is an Apache 2 module that solves the problem of limiting the bandwidth usage of users, virtual hosts, and destinations. When the configured transfer limit is exceeded, mod_cband will redirect all further requests to a location specified in the configuration file. The module can also limit download speeds and maximal requests per second for virtualhosts, users, and remote clients.
Tvheadend is a streaming server/relay supporing a variety of sources and multiple output formats. It is primarily intended to be used for receiving TV (DVB, Analog, IPTV) and to transmit it using a number of different output formats to subscribers. Together with powerful DVR (Digital Video Recorder) features, an advanced EPG and a web-interface it can be used as a TV distribution hub.
lb is a very small and efficient libevent-based benchmarking tool for HTTP servers. It has been implemented with the main goal to provide a safe and quick replacement for the Apache 'ab' tool. Since its first release, it comes with the ability to benchmark several HTTP servers at the same time, theoretically limited only by operating system limits.
