For MySQL, migrate region tables to the MyISAM storage engine rather than InnoDB
Using MyISAM proves vastly faster for persisting scene objects. For instance, a scene object that took 9 seconds to persist before now takes 1. This also improves the experience of loading large OARs. We don't use any of the transactional features of InnoDB. The only thing that may have an impact is that InnoDB does row locking on inserts while MyISAM does table locking. However, field reports say there is no noticeable difference.
