  Disabled logging of SQL statements
  Doing negative caching for config values, special logfile for database optmisations
  Saved searches now can search for tags as well
  Deactivating the test output in db engine
  Speed optimisation by enabling the posibility of the MySQL fulltext engine
  Performance tests
