When only a couple thousand copies you probably don’t want to pay for the speedup, eg even going an extra 4x decreases the number of copies by 8x.
I also think when you don’t have control over your own hardware the speedup schemes become harder, since they might require custom network topologies. Not sure about that though
Why only 5x? Didn’t you yourself argue it could easily be made to go much faster than that?
