 * Not moving files from new/ to cur/ directory
 * Not renaming files when changing message flags
 * Not readdir()ing directories (although maildir_very_dirty_syncs=yes helps a lot with this)

Basically less disk I/O and making it possible to have mailboxes with a huge number of messages without everything slowing down horribly.
