I wouldn't expect this to push any objects at all, since you're pushing
to a repository that already has all of the objects contained in
`master`.

A more representative test might be something like:

    $ git clone https://github.com/JetBrains/intellij-community.git --bare
    $ cd intellij-community.git
    $ git repack -adb
    $ git rev-parse HEAD >in
    $ time git pack-objects --revs --stdout <in >/dev/null
    # move the bitmap away so we don't use it
    $ mv objects/pack/pack-*.bitmap{,.bak}
    $ time git pack-objects --revs --stdout <in >/dev/null

Thanks,
Taylor
