There are some OS differences between the old and new servers : old is
running CentOS 5.7 while the new is running 6.0.
Old server has atime enabled while new has relatime mount option
specified. Both are running PG 9.1.1 from the yum repo.
Also the old server is using ext3 while the new has ext4 (with
discard/trim enabled).
