[Ocfs2-users] OCFS2 slow when using 'find' and 'du' commands

[Robert Abbate]

we've noticed that once we have grown to have thousands (21,839) of
sub-directories running linux commands such as 'find' and 'du' are very
slow. we compared them by running them directly on a hard-disk with the
same file and directory contents

find ./directory/* -type f -mmin -60

(21,839 directories)
ocfs2 = 10 minutes
direct  = 30 seconds

Are there any tweaks we need to make to help improve performance of these
commands when many sub-directories exist?

ocfs2 nodes = 3
