By what metric? Jeez. People, you need to get your blood checked. There is no one-fits-all dosage. In winter, 4000 IU/d was enough to raise my blood levels well into the excessive range.

My 4000 units were after blood testing and also after genetic testing which showed some VDR mutations that might benefit from supplementation. As mentioned in another comment, that dose brings me slightly over 30 ng/ml, so basically borderline ok.
I fully agree that supplementation should always be combined with both blood testing and also a general medical evaluation.
