All changes to the database in SQLite must be done within a transaction, so if there isn't one in progress one will be started implicitly, i.e. each change will be done in a separate transaction. Since committing a transaction is a fairly expensive operation - on some filesystems ridiculously expensive - it should be done as sparingly as possible. In tests on my Galaxy S, this change makes the update between 2500% and 4500% faster (for slightly over 100 applications).
