>+        <para>A vnode is the internal representation of a file or
>+          directory.  So increasing the number of vnodes avaliable to
>+          the operating system cuts down on disk I/O.  Normally this
>+          is handled by the operating system and does not need to be
>+          changed.  In some cases where disk I/O is a bottleneck and
>+          the system is running out of vnodes, this setting will need
>+          to be increased.  The amount of inactive and free RAM will
>+          need to be taken into account.</para>

>+        <para>If the current vnode usage is near the maximum, upping
>+          <varname>kern.maxvnodes</varname> by a 1,000 is probably a
>+          good idea.  Keep an eye on the number of
>+          <varname>vfs.numvnodes</varname>.  If it climbs up to the
>+          maximum again, <varname>kern.maxvnodes</varname> will need to
>+          be increased further.  A shift in your memory usage as
>+          reported by &man.top.1; should be visable.  More memory should
