In terms of a pure speed web server for static data (where mmap is a big win)
the right way[TM] is probably to preindex all the files you can serve and
to mmap the lot into memory at setup time with a one page gap between them
that contains precomputed HTML headers for each page. You then build an
index of the pointers to each URL, feed all the URL's through the GNU
perfect hash program to generate a hash and each web page serve becomes

write(socket, x->data,x->len)

if you want to play total speed then someone should write a web server that
does this and uses clone() to create all of its threads. I suspect you can
probably serve a web page in about 20 syscalls, less if the headers arrive
in one chunk from the client.
