Up late because I had to rebuild my zfs pool on my main workstation. I intended to start the replication and go to sleep, but that didn't happen.
Things seem much better right now, but time will tell.
Special thanks to @jimsalter for keying me in to my Samsung EVO drives lying about their block size and likely the cause of my crap #ZFS performance of my home directory since 2017... I probably should have asked him earlier 馃う
