Need some tricks survive with BTRFS

Unfortunately SNO here on the forum just states what they experienced using BTRFS.

Information to SNO's regarding ZFS/btrfs vs. ext4 on spinners

Hi all, My storage node wasn’t performing as it used to, and I started looking into it. I set it up 13 months ago, on 1x 3TB 7200rpm drive, to get into the platform. Today, it was simply not performing; loading the dashboard took 10-15 seconds. I had 3,6 million files on 2,8 TiB of storage, which shouldn’t be an issue. However… it took 15 seconds to ‘ls’ in a blob folder. It took 3 hours do run a ncdu on the volume… It took almost half a day for the runner to traverse the drive after restart. …

You may just check all Topics tagged btrfs to see that.

My simple tests does show that BTRFS is slower than ext4 especially for storagenode, but you just need to test it yourself.
