[xwiki-devs] Velocity parsed template caching

Hi, I've done some XWiki profiling and it seems that the biggest bottlenecks are Velocity template evaluating (in XWikiVelocityRenderer) and Lucene Index Updater thread... Did you think about using StringResourceLoader (or something similar) instead of Velocity.evaluate()? I believe caching parsed ASTs rather than reparsing the same strings everytime could significantly improve overall performance. Here you can find some interesting discussion about StringResourceLoader --> http://www.mail-archive.com/user@velocity.apache.org/msg02135.html Well, I'd like to give it a try. Do you know any traps/gotchas I should be aware of? Kind regards Lukasz
