Significant Degradation in ARM recalculate performance

Hi,

Our user perform a recalculation for FCM ARM application.

Here are the stats month by month:

In Dec, the Average was 54 mins, Max  90 minutes, Min 41 minutes

In Jan, the Average was 72 mins, Max  106 minutes, Min 54 minutes

In Feb, the Average was 142 mins, Max  180 minutes, Min 95 minutes

As you can see, the performance is getting worse. It is the 3rd month our

user use this application, and they want to know why the relcalculation

is getting significantly slower, especially in the third month.

Could you please advise what to look to identify the cause of the slow performance in

recalculation? Is adding new map with like condition for profile dimension have
