Uh-oh. needs a break. After success on the small computer, trying #FreeBSD on the big main computer didn't go well at all: it wasn't even about yotube or videos, everything was slowing down and the logs were full of GELI error E_NOMEM.
I need to pause and read the memory requirements of ZFS. Maybe 32G isn't as much as I thought. And I don't think it's the processor - Ryzen 5 with 16 threads is not the dead horse.
