I think this means:
        <Context path="/cocoon" docBase="..." debug="0" reloadable="false"/>
in the Tomcat's server.xml.


If you change
  <program-generator logger="core.program-generator">
    <parameter name="auto-reload" value="true"/>
to false, this will disable XSP reloading.

And,
  <sitemap class="org.apache.cocoon.sitemap.SitemapManager"
           file="sitemap.xmap" reload-method="synchron" 
check-reload="no" logger="sitemap"/>
will disable sitemap reloading.
