tinyhttpd

tinyhttpd is a minimum functional HTTP server written in the C programming language.

Compile and run

For now tinyhttpd only support Linux 2.6 or later.

Please make sure you have cmake installed.

mkdir build && cd build
cmake .. && make
cd .. && ./build/tinyhttpd &

By default the server runs on port 8008, if you want to assign other port for the server, run it as ./build/tinyhttpd port &.

In order to avoid showing too much stdout/stderr message, you can run ./build/tinyhttpd [port] 2>&1 >tinyhttpd.log & to redirect both stdout and stderr to a log file.

Programming model

  • epoll
  • non-blocking I/O
  • threadpool

Performance

I have made a small performance test with Zaver, a fast and efficient HTTP server(I have learned a lot from it). In a way it was not a fair comparasion, for the number of total transferred bytes was not equal and the processing logic in tinyhttpd is relatively simple.
