Let me share this week's progress.
Earlier this week, I finished my tests with Parrot for its releases 2.7 - 3.0. Including rurban's profiling, we now have data (reliable to some extent) for the commits in this range. The main objective for the profiling was to determine the highest overhead to be targeted next for refactor.
(For the list of all the identified overheads, please take a look at - http://wiki.enlightenedperl.org/gsoc2014/ideas/improve_performance_of_me...)
