Here is some more interesting info on EL performance. Looks like Eclipse also had problems and they managed to speed it up significantly. http://dev.eclipse.org/mhonarc/lists/wtp-jsf-dev/msg00271.html anonymous wrote : WTP 2.0 RC0 is targeted to release with a badly needed improvement to JSF EL validation performance. | | Based on performance benchmarking you should see worst case performance roughly twice as fast and average case as much as 300 times faster when validating EL expressions involving #{bean.property} type expressions. I am also seeing a speed improvement of about 3 times when running my larger EL validation test suites. | | Special thanks to Matthias Fuessel for providing us with a targeted caching mechanism to make this performance improvement possible. | | To see all the details of the issue see: | | | https://bugs.eclipse.org/bugs/show_bug.cgi?id=163890 Can something like this be done to JBoss EL?
