Only write IO during the load spikes. No compression, no deduplication. 12 volumes (including snapshots). Spinning disks. Medium workload; file sizes are all over the map since this hold about 30 user home directories.
Interestingly enough, the problems which had persisted for many weeks went away when all snapshots were removed. btrfs-transaction spikes disappeared. Memory usage went from 30G to under 2G.
