Can you point to memtest source/docs? In order to understand the effects of ZFS, you have to test on the same machine with and without zfs enabled, and probably with and without loading the ARC from accesses. There is also datasize limits, and swap space. > Even if it did work, this can prevent large programs from launching so > I think for a desktop it's not a good default. Or would it not do > that? Sorry if I'm misunderstanding how this should work. I don't know of any programs that need 8G to start. There are many things going on about memory, and to draw reliable conclusions it's necessary to have a controlled experiment changing only one thing. I'm not saying you don't have a point, or haven't found something. Just that without a without-zfs/with-zfs repeatable pair, it's hard to understand.
