<h3>Tuning</h3>

After running the first bench, and watching the system under
top, it becomes strikingly clear that disk i/o is the bottleneck,
with 50%+ of the time spent waiting for disk.  The reason
is that state management for $Session and $Application uses
SDBM_File, or optionally DB_File, databases on disk to store data, 
and is highly i/o intensive.
<p>
The <i>trick</i> then is to relocate the <tt>StateDir</tt> 
to a fast cached file system.  On Solaris, this happens to 
be /tmp/... by default, but on Linux and WinNT, the file systems seem
to be cached automatically, so you may not need to do anything
except locate <tt>StateDir</tt> to a secure, non-browsable, location.
Using a cached or RAM file system will also spare your disk, which is good 
as it is often the first thing to go on your box.
