Great read. I wonder if the make -j modification wasn’t scaling things across all cores because it was using the physical core count (number of cores) versus the logical core count (number of core threads).

Or perhaps the code wasn’t modified to spread the work across all processor core groups (a Windows thing to support more than 64 logical cores).
