Hello,
I've been experiencing slow find performance on XFS ever since I started specifying su/sw parameters at mkfs.xfs. This happens even on a newly created XFS filesystem, after all of the data has been restored from another backup server via rsync.
The files on this server are almost entirely large, 50MB to 20GB, with an average of around 350MB per file. There are about 70,000 files and about 4,600 directories.
When running the find command "find /array", it will list files and directories very slowly, all while using very little I/O or CPU. Keep in mind, this particular server is entirely idle, no other activity is going on.
Here's some general information about the system.
