Can you send your filesystem geometry (xfs_info output)?
And any performance numbers you have for each of the different
geometries you've tried would be good to see too.
The difference moving from the default 256 byte inode to any
larger inode size is where the big gains are seen, I wouldn't
expect too much improvement going from 1k to 2k. Though it
may help a bit for small directories with ACLs... (and small
directories in general).
cheers.
