       <p>Operating system choice is largely a matter of local
  -    concerns. But a general guideline is to always apply the latest
  -    vendor TCP/IP patches. HTTP serving completely breaks many of
  -    the assumptions built into Unix kernels up through 1994 and
  -    even 1995. Good choices include recent FreeBSD, and Linux.</p>
  +    concerns. But some guidelines that have proven generally
  +    useful are:</p>
  +    <ul>
  +      <li>Run the latest stable release and patchlevel of the
  +      operating system that you choose.  Many OS suppliers have
  +      introduced significant performance improvements their
  +      TCP stacks and thread libraries in recent years.</li>
  +      <li>If your OS supports a sendfile(2) system call, make
  +      sure you install the release and/or patches needed to
  +      enable it.  (With Linux, for example, this means using
  +      Linux 2.4 or later.  For early releases of Solaris 8,
  +      you may need to apply a patch.)  On systems where it
  +      is available, sendfile enables Apache 2 to deliver
  +      static content faster and with lower CPU utilization.</li>
  +    </ul>
