TableView resizeColumnsToContents Slow on large sets of data.

I would have thought that TableView->sizeHintForIndex() returns the sizeHint of the delegate used for that cell. It does not make sense that it would return a different sizeHint since the table uses the delegate's sizeHint to make the cell the correct size.

The delegate is only a part of the size calculation aspect.

Sure it does. What if you drag the table header with the mouse increasing the column/row size? Should the sizeHint still be what the delegate reports?
