Could you provide us with the New Visualizer display of a small-K
immutable download and of a large-K immutable download so that we can
compare the two?

And could you likewise do runs of those two cases with the "--profile"

Thank you very much!

Or, even better, let's automate all of the above and have buildbot do
it regularly from now on. :-)
