      Async profiler shows that applications spend up to 10% in itable_stubs. The generated itable_stub scans itable two times while it can be done in a single pass.


      Update: I have working ppc version, which is "only working" kind of implementation. There is no performance benefit. I'm planning to look further into it, but if you can provide additional change which will guarantee the performance improvement... You're most welcome!!!!
