Optimum level for Exchange Mailbox Archiving Task

Hi Guys,

Im wondering if you could help me or suggest the optimum level that would suite.

We had a contract company that came in and installed EV11.0.1 for us

There is a Exchange Mailbox Archiving Task that runs, But we are noticing that our CAS server CPU cores are running at 84 - 95% when the task is running.

My question is what would be the recommendations.

Would the below screenshot be correct for the most optimum level for EV to run

Any Help is appreciated.
