Note in the bar charts how the 28-core system is faster, when compared to the 36-core. The 28-core does not suffer from the "processor group" issue fixed in D71775 <https://reviews.llvm.org/D71775>, the 28-cores/56-threads all fit in a single "processor group", so they are all available to the application; while the 36-cores/72-threads are projected to the application as two "processor groups", out of which only one is used by default. After D71775 <https://reviews.llvm.org/D71775>, the 36-core is evidently faster.
