    Hi Experts,

    Is there any performance impact if we run DBCC CHECKDB? if yes,then what?

    We have a 3TB database and we are planning to run a CHECKDB?

    Please advise.

    TIA

    Hi Experts,

    Is there any performance impact if we run DBCC CHECKDB? if yes,then what?

    Yes. Heavy CPU and IO load.

    We have a 3TB database and we are planning to run a CHECKDB?

    Good idea. Regularly I hope.

    If you're concerned or are already bumping into issues getting consistency checks to complete on a 3TB database you can consider splitting the workload:
