      footprint (~500KiB for 10k idle connections), with minimal system calls and
      memory allocation.  Lwan contains a 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.  Features include: mustache templating engine and IPv6
      support.
