I already updated to 3.2.4 and started the same "find dir" command again
that previously took 100 min to run. It has been running now for over 30
min ...
Should this "find" run time also improve ?
Or will only unlink run time improve ?
I expect both of them to change similarly, or not? Wrong assumption?
Do I have to mount the XFS partition with some new/old/special option?
Thanks again,
Richard
