In particular, the dpkg package manager is known to run significantly slower on ext4, causing installations using the server or alternate install CD to take on the order of twice as long as before. ext4 does not guarantee atomic renames of new files over existing files in the event of a power failure shortly after the rename, and so dpkg needs to force the contents of the new file out to disk before renaming it in order to avoid leaving corrupt zero-length files after power failures. This operation involves waiting for the disk significantly more than it strictly needs to, and so degrades performance.

that would have been good to know a few hours ago.
