Lwan is a high-performance & scalable web server for glibc/Linux platforms.

In development for almost 4 years, Lwan was until now a personal research effort that focused mostly on building a solid infrastructure for a lightweight and speedy web server:
* Low memory footprint (~500KiB for 10k idle connections)
* Minimal memory allocations & copies
* Minimal system calls
* Hand-crafted HTTP request parser
* Files are served using the most efficient way according to their size
- No copies between kernel and userland for files larger than 16KiB
- Smaller files are sent using vectored I/O of memory-mapped buffers
- Header overhead is considered before compressing small files
* Mostly wait-free multi-threaded design
* Diminute code base with roughly 7200 lines of C code... More Info »
