Running the DM/PM rules is CPU- and memory-intensive because each rule is issued for every sub-rule linearly. If you do not use DM/PM rules sparingly, it becomes difficult to manage the number of DM/PM rules or sub-rules applied to a call. Ribbon recommends issuing no more than 80-100 sub-rules per call.
