The decision to immediately fsync() all files written to disk has a detrimental influence on dpkg's performance, especially when unpacking large packages. On my system which has a 2.5" hard disk with an ext4 filesystem, installing emacs23-common (containing 2123 files) with a hot cache takes 76 seconds, almost all of which is spent during unpacking. With dpkg 1.15.5.6, it takes 5.3 seconds, including processing three triggers. This is really painful. :-(
