Now that I look again, it seems that the btrfs-cleaner process is still running. CPU isn't much of an issue on this box. Its a dual quad E5620. 8 cores, 16 threads. Looks like most of my load is wait from the cleaner process hammering the disks. I deleted about 10 snapshots I think. Should this take 4 days to clean up from that?
