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. [unhandled content-type:application/pgp-signature] | |
