I don't really think that's true. It certainly hasn't been optimized
heavily yet, and more concentration is definitely going into features at
present, but that's not to say that performance isn't a goal in the
completeness of time. Also there will be lots of people for whom this is
more of a priority right now and thus they will be the ones perhaps
contributing the patches to help edge things in that direction :)
