Already in December we launched the all-Cocoon redesign of our SWX Swiss Exchange main website http://www.swx.com.
Initially we had to fight some performance problems due to XSLT transformation with interpreted Xalan taking around one second per page (after profiling and optimizing the stylesheet). Following http://wiki.apache.org/cocoon/XSLTC I then tried the XSLTC compiler coming with Xalan 2.6.0, and it blew me off my feet. The compiled stylesheets are an order of magnitude faster than interpreted Xalan, and solved all our performance problems. There a few gotchas where the compiled stylesheets do not work properly. Up to now we found three cases in our XSLT code where XSLTC behaved differently from interpreted Xalan: http://issues.apache.org/jira/browse/XALANJ-2030 http://issues.apache.org/jira/browse/XALANJ-2031 http://issues.apache.org/jira/browse/XALANJ-2032 All of them are fairly easy to workaround (and most likely won't show in your stylesheets), and only small nuissances compared to the gain in speed. Also XSLTC does more compile time checks catching errors such as calling undefined template names which makes interpreted Xalan to throw up only at runtime. My recommendation: use interpreted Xalan for development, use XSLTC for stylesheet validation and production but rigorously compare output of interpreted and compiled stylesheets. NB I don't see any memory leak which apparently plagued earlier Xalan/XSLTC versions. Happy New Year to everybody, Alfred This message is for the named person's use only.
