Hi, a while ago I was setting & reading extended attributes to ~25000 files in a directory structure on an XFS filesystem. The files were usually a few MB in size, but some where up to 2GB in size.
Anyway, I *felt* that setting or reading these xattrs was going very slowly. While the storage may be not the fastest, stat()'ing these files was fine, but getfattr/setfattr took very long. I got curious and while it turned out that the slowness was related to the wrapper script I used to read/set those values, I created a little test suite to 1) create a few thousand files and 2) do xattr operations on them and see if xattr performance was filesystem specific: http://nerdbynature.de/bits/xattr/ Not very sophisticated, true. But it was interesting to see that ext3/ext4/xfs behaved kinda well for all these tests; btrfs/jfs/reiserfs sometimes took way longer than the others.
