The priority date is equal to receive date.(receive by USCIS)
When NVC sent of response for my inquiry beside date of birth, type of visa CR or IR they wrote this priority date.
I think it might be important for embassy ? Not sure.
Yes, you are correct when the queue gets longer - priority date is used to process/adjudicate cases.
