Bergman Precedence: bulk Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit You do have to be careful in version 9, though, since the really is an MBRC - which is the system stat which is the average size of multi block read count actually achieved over a time period, rather than the value requested in the db_file_multiblock_read_count parameter. (The real MBRC is used for costing when the new cpu_costing method is switched on, an adjusted dbf_mbrc is used when the traditional io_costing method is the only thing in place).
