f.modulo command

The f.modulo command in the DM account calculates a file modulo, based on estimated file characteristics. The f.modulo command prompts for the number of items, item-ID size, and item size.

This returns a recommended modulo, taking into concern the frame size of the machine and inline/pointer items.

Specifying a large item-size (greater than 85% of the frame size) results in items being computed as pointer items, which produces a very small modulo.
