Customize your cache settings using the forms below.
You should never set your cache sizes to total more than half of your
total JVM memory. By default, most JVMs are configured to use 64 MB of memory,
although the default may vary or have been changed on your system.
<p>
Setting the caches too large will not result in increased performance. Instead,
tune your cache larger only as long as it results in greater effectivness over 
time (as measured on the <a href="cache.jsp">main cache</a> page).
