There have been a number of changes to speed things up recently. Please recheck with a more current version of systemd. Also, is this btrfs? If so, btrfs cannot handle our write pattern particularly well, and can get excessively slow. On current development versions of systemd I thus changed it to disable the COW mode for journal files, which should make this less of a problem.
