I understand "interface devirt with value profiler" item from Rana's list as the same task. + "Loop versioning" optimization in Jitrino.OPT - Implement versioning

Yes, our (Jitrino.OPT) loop optimizations are in a bad state today :) BTW the page I've created recently ( http://wiki.apache.org/harmony/JIT_Tasks_For_Beginners ) could be removed and all the tasks listed there are added to the new page. Another proposal: mark every item with a level of expertise required for a volunteer: Novice, Advanced, Expert This will help both to novice and expert users: Novice will know if the task is rather easy. An expert will have a hint that the task worth to be discussed about side effects more carefully... -- Mikhail Fursov
