Github user MLnick commented on the pull request:
    @mengxr <> at the risk of adding to your
    workload... I think (license issues aside since I suppose both Breeze and
    MTJ are affected in the same way), that it would be great to get a sense of
    MTJ performance (which should in theory be as good as or better than
    One issue that came up with MLlib developers initially was that Breeze
    performance suffered due to heavy implicit use / object creation. It would
    be good to know if this is not the case anymore (ie if recent dev had fixed
    this). If not, MTJ would be a good alternative (again, wrapped in a
    lightweight DSL if we wish).
