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.
