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.
