Testing with data from my 67M FileStorage, read and write performance see=

be roughly 1.5 times slower than FileStorage, although with a much higher=

usage.
DirectoryStorage performs some of its writing asynchronously, after the=20
transaction has completed. If you write fast enough then the queue to the=

other thread fills up, and writing degrades to roughly 3 times slower tha=

FileStorage.
