I have found the following statement in the docs: "It is also perfectly reasonable to mix and match compile time and load time though. If you have load-time transformation enabled, precompiled aspects are not transformed when they are loaded and ignored by the classloader transformer." But I guess that does not really have an impact on the performance. If I have only 10 classes which get weaved and 200 that dont, loadtime weaving still consumes almost the same amount of time, because it has to scan all the 200 files that are not going to be weaved. Is this opinion right? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249256#...
