client import very slow due to high import/export swaps

Dear SAP community,

We have an issue happened during a client import action. We got 14 GB exported client data and in these times it's running for 50 hours. In first circa 14 hours import went well but later import/export start dramatically increased (now about 1.300.000) what incredibly decelerated import process. My question is if there is any possibility/solution how to decrease import/export swaps during active import (meant to not cancel import and start over 😊) ?

Thank you very much for yours eventual answers...
