That seems to have brought things more into line with what Ayoub saw. I did get some small regressions, but I suspect those are not a big deal. (For instance, on both machines I also noticed the occasional "truncate table" would take longer than the others, despite my scripts' best efforts to steady a CPU core and pin postmaster and children to that core.)
Thank you both for the benchmarks. Results look good to me!
