But they do indeed come at a price: Smaller number of LUNS means less paralleism in the driver, means less performance. More tables in the same dbspace means that you will# find out mutex contention, athing never seen before And there are many more..... We do have superior performance - as every - not necessarily because we avoig large chunks, but who knows? cu, dic_k -- Richard Kofler SOLID STATE EDV Dienstleistungen GmbH Vienna/Austria/Europe
