Right which is part of why dictating the implementation language up front as part of the bounty is a mistake. They should have put the bounty on the speedup factor they're looking for and let it sort itself out.
My not-completely-naive guess is an expert optimizer can get the improvement they're looking for with only small parts or maybe even none of it rewritten in another language.
