Hint 3: "Apache".

Apache under Linux uses sendfile() to copy static content directly from the
filesystem to the socket. This is very efficient. I saw the same bizarre
results on a FreeBSD system, but found that dynamic content showed
different performance characteristics, which led me to the realization of
how this happens in the static case.
