Yeah, went and did that for my 4 node machine, its got a ton more cores, but I
matches the warehouses to it:

-a43455a1d57 tip/master

979996.47 1144715.44
876146 1098499.07
1058974.18 1019499.38
1055951.59 1139405.22
970504.01 1099659.09

988314.45 1100355.64 (avg)
75059.546179565 50085.7473975167(stdev)

So for 5 runs, tip/master (which includes the offending patch) wins hands down.

Each run is 2 minutes.
