The article linked to a set of posix-spawn benchmarks[1] that seemed to indicate that while fork/exec time scaled linearly with resident memory on Linux, it did not scale at all on macOS.

First of all, I was somewhat confused by that due to the availability of copy-on-write; I wouldn't have expected fork/exec time to scale up that way.

Second, I was surprised that there wasn't an attempt to explain the behavior difference between the two systems. Can someone familiar with either or both point towards an explanation for why that's the case? It seems very odd.
