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 -- = Richard Ems mail: Richard.Ems@Cape-Horn-Eng.com Cape Horn Engineering S.L. C/ Dr. J.J.
