Accounting Hub - What if I split a huge mapping set into multiple smaller ones?

I have a huge mapping set (550.000 records) based on something like 10 different input fields to determine the proper natural account in output.

What about to create for example 55 different mapping sets with 10.000 records each, and then to assign the 55 mapping sets to the same account rule, with priorities from 1 to 55?

Will it improve performances?
