cserv is an event-driven and non-blocking web server. It ideally has one worker process per cpu or processor core, and each one is capable of handling thounds of incoming network connections per worker. There is no need to create new threads or processes for each connection.

I/O multiplexing is achieved using epoll.

• Single-threaded, non-blocking I/O based on event-driven model
• Multi-core support with processor affinity
• Implement load balancing among processes
• Hook and optimize blocking socket system calls
• Faciliate coroutines for fast task switching
• Efficient timeout handling
• Builtin memcache service

At the moment, cserv supports Linux based systems with epoll system call. Building cserv is straightforward.

$ make

Start the web server.

$ ./cserv start

Stop the web server.

$ ./cserv stop

Check the configurations.

$ ./cserv conf

By default the server accepts connections on port 8081, if you want to assign other port for the server, modify file conf/cserv.conf and restart the server.
