After mounting XFS with inode64 I see performance improvement (open()
now takes ~3ms vs ~15ms previous) although it's still not something I
would expect (~150us.) On Dave's suggestion I will give a shot CentOS
6.x and see if that makes any difference although this needs to be
monitored over longer period of time to reliably tell if that make a
difference.
