It's a fact, provided the transaction read-write attribute is true (the
default). For a read-write transaction the engine sets things up for
creating and rolling back new record versions if required. Cleaning up
after a Commit costs less than cleaning up after a Rollback.

But for a transaction set to be readonly, there is no difference.
