Improvement was made on SetReportTree() method, which is used to generate a results worksheet. So when there are many operations involves report sheet, you will get at least 10% time saving on calculation.

Besides, if there are many column formula operations, recalculation was done one by one in previous version and the time maybe a little long. But now in Origin 2020, you will see that all recalculation can be done in the same time and the calculation is very fast.
