This box contains the time, in milliseconds, required to read one 4 KB page into memory. It is used to determine the cost of I/O during query optimization.
If this time is not the same for all containers in the table space, the value used should be an average of the transfer time for all containers.
To change the time, use one of these methods:
Transfer is calculated using the following formula:
transfer = ( 1 / transfer rate in MB per second ) * 1000 / 1024000 * 4096
