Both databases belong to the same Objectivity DB federation and have the same schema. An alternative on NT could certainly be reached in short time. The FD is created with a configured page size of 4096 Bytes. It has been separated to allow faster access to the RunSum data, which is less quantity but used more frequently. The DB write performance is not expected to be of any importance, since new objects are only created after a RunStatistics collect cycle has taken place.
Retrieve performance is adequate by using the run number index.
