1. Create 10000 blogs and ratings entries by running the attached Groovy script
2. Create a new site "testsite"
3. Manually export the completely empty testsite with default options

Result: The export of the empty site takes about 4 minutes (depending on your machine's resources) because all the 10000 ratings will be exported also (the blog entries will not).

The reason is that the RatingsEntry model does not have a groupId, and therefore PageRatingsPortletDataHandler will not be able filter them by the exported site's groupId when fetching the ones to export. Only the entities that they are rating have a groupId so we have to filter for that.

Note: This anomaly affects site creation from site template also. E.g. creating a new site from the Intranet Site template takes about the same amount of time because of this unnecessary export and import, which also doesn't make any sense.
