This software is a basic Echo Client+Server tool that utilizes the Niels Provos libevent library. It provides a simple solution for passing data between the client and server.
In essence, libevent is designed to replace the event loop found in event-driven network servers. Instead, an application simply needs to call event_dispatch() and then add or remove events dynamically without any need to change the event loop. Currently, libevent supports several options including /dev/poll, kqueue, event ports, select, poll, and epoll.
It is noteworthy that the internal event mechanism in libevent is entirely independent of the exposed event API. This means that a simple update of libevent will provide new functionality without requiring the redesign of the applications. This feature allows for portable application development and provides the most scalable event notification mechanism known to operating systems.
Often, Libevent can be used for multi-threaded applications with the guidance of Steven Grimm's explanation. Libevent should compile on Linux, *BSD, Mac OS X, Solaris, and Windows with ease. Overall, this Simple Echo Client+Server is an excellent option for those seeking to test performance within a network server.
