                          Tunable Kernel Parameters

 NAME    [Toc]    [Back]
      sendfile_max - maximum number of Buffer Cache Pages used by sendfile

 VALUES    [Toc]    [Back]
      0 unlimited

    Default    [Toc]    [Back]
      0 unlimited

    Allowed values    [Toc]    [Back]

    Recommended values    [Toc]    [Back]
      0 unlimited

 DESCRIPTION    [Toc]    [Back]
      This variable is used to limit how many Buffer Cache Pages the
      sendfile() system call can use.  This might be useful in a machine
      that has a large sendfile() load but is limited in memory.

    Who Is Expected to Change This Tunable?

    Restrictions on Changing    [Toc]    [Back]
      Changes to this tunable take effect at the next reboot.

    When Should the Value of This Tunable Be Raised?
      This tunable might be useful in a machine that has a large sendfile()
      load but is limited in memory.

    What Are the Side Effects of Raising the Value?
      Possible side effects would be slower sendfile() performance.

 WARNINGS    [Toc]    [Back]
      All HP-UX kernel tunable parameters are release specific.  This
      parameter may be removed or have its meaning changed in future
      releases of HP-UX.

      Installation of optional kernel software, from HP or other vendors,
      may cause changes to tunable parameter values.  After installation,
      some tunable parameters may no longer be at the default or recommended
      values.  For information about the effects of installation on tunable
      values, consult the documentation for the kernel software being
      installed. For information about optional kernel software that was
      factory installed on your system, see HP-UX Release Notes at
