BETA: 2 server optimization configs (thanks nik)

1. Database Cleanup - in most cases this is just slowing up the server start, on a big servers it takes up to 1 min or more to cleanup the database, and in the most cases ending up with 0 elements.

2. Connection Close Time - Higher number fixes the "Unclosed Connection!" errors, caused by the big queries
