    Well, supposedly any such team would need to start by creating a set of
    tools and benchmarks that could be used to quantify perfomance, get buy-in
    from the project that these give good measures (iterate until done) and
    then set up a bunch of machines to track there are no regressions?
    Followed by then starting to work towards eliminating problems 8-)

    nah, don't be too hard on them. they are volunteering for a large amount
    of hard work 8-)
