In the last few months jnthn has added optimizing stages to the Rakudo/NQP/backends compiler stack. In his latest blog post he outlines these stages and notes some early results from a few things he and timotimo have already done ("Array and hash access is more than 3 times faster, most multi-dispatches are now enormously cheaper").

There's other news too, so even if you're not ready for -Ofun the linked blog post is still worth a read if you are interested in P6.
