I think we long wanted this functionality but never implemented it.

The other thing in those graphs (a bit annoying to see because the
scale differs from graph to graph), but the start-workload seems to run
faster at least on the writer node, but I am not sure if that's part of
the question of just a normal variancy of the environment.
