I will try to install a > 3.2 kernel and will create new XFS partitions with "-i size=1024", since we use ACLs a lot for user access. Is there a chance to change existing XFS partitions to "-i size=1024" ?Unfortunately not. Note that the speedups in 3.2 only matter for out of line attributes - once you store the ACLs inside the inode the code that makes it dog slow in old kernels is never used.
Ok, I see, many thanks. So 1. use kernels > 3.2, if XFS partition was not created using "-i size=1024" 2. if XFS partition was created using "-i size=1024", kernels < 3.2 will also be fast while unlinking files with out of line attributes Right?
