Assuming I've never used APE itself:

    Silly question 1: what's the general speed compared to a regular
    `pickled' ZODB over FileStorage?

    Silly question 2: one thing I've noticed is that the ZODB takes time
    to load object state (Connection.setstate and Storage.load) from the
    database -- would it be possible to load portions of the state
    lazily when using APE, given that it would now be possible to grab
    a value for the specific attribute referenced and not the whole blob?

        (I'm not sure how much this would improve things, given that the
        current model allows us to read the whole state only once, which
        may very well be generally faster -- just curious)

Take care,
