I'm talking about the time it takes for the `rm` command to finish. I've started the habit of running all `rm` commands in the background on btrfs.

  If it's reproducible, my suggestion is to strace the rm command and find out what it's doing that's taking so long; and post it to the mailing list: https://btrfs.wiki.kernel.org/index.php/Btrfs_mailing_list https://btrfs.wiki.kernel.org/index.php/Btrfs_mailing_list

    Recording the kernel profile with perf would be more useful, I think. strace would probably only show long "unlink" syscall.

      Yeah, and if perf is unrevealing, sysrq+t.
