No, quota is off for me. This is a three-device btrfs desktop system. Quota has no real use for me (except maybe for subvolume accounting). I first thought this may be related to having zcache enabled, turned it off. But anything that changed is when memory stress arises my system stays more responsible and does not go havoc on the CPU. I switched to zswap instead, since then swap usage is much lower. But still it does not help if memory is mysteriously used somewhere. At least IO stress is lower now with that setting and I am better able to cleanly shut down programs and the system for reboot.
