Hi Blake, I did performance tests back then, it actually makes a significant difference on most databases, especially for batch imports. Even more if the database is not running on localhost. Not sure about the actual numbers though. You can always switch to the database sequence generator for IDs if you want to try it out yourself, I think it's still available and it's a simple configuration option.
