OK, I've done a little benchmark.  The differences are marginal.

* Execution times of the command you proposed (each averaged over five
  runs):

  With XATTR:    55.4 s +/- 2.1 s

  Without XATTR: 60.4 s +/- 1.0 s

* The directory /tmp/sandbox/ (without /tmp/sandbox/.beagle/):

  - Size:

    $ du -s --si /tmp/sandbox/
    95M     /tmp/sandbox/

  - Number of files:

    $ find /tmp/sandbox/ -type f | wc -l
    1911
