1) http://cocoon.apache.org/2.0/performancetips.html 2) caching, if it is an option - http://wiki.cocoondev.org/Wiki.jsp?page=WritingForCacheEfficiency - caching database results is not implemented by default in cocoon so you'll need to write your own code to interface with the cocoon cache system. See the page above, and the xsp cache examples. 3) consider ways to offload heavy processing from your xslt. you can often do this in ways that don't mix presentation with logic. 4) this is mentioned in the doc at #1, but consider pre-generating these reports (or portions of them) via command line cocoon. 5) And of course, buy beefy hardware! If that's not possible, at least make sure your machine is not "thrashing" - spending time paging memory out to disk and back in because it is memory starved. Also, if you have the memory available on the machine, make sure you have allocated it for use by the jvm when you start up your servlet container.
