How is "overall performance" measured? The measurement used determines the level of performance using that metric
. You can come up with a number of different tests that people would subjectively call an overall performance metric, and show results where the system with a faster long-division calculation has worse performance on the overall metric. The answer is "not necessarily" and therefore false.
I don't consider this a good question, because it really is asking you to guess at the instructor's assumptions. All things remaining equal, this statement is true. In general, given two "comparable systems", the statement is also true (which means not always, but usually true). But since he hasn't stated his assumptions, you have to ask yourself is he a detail-oriented kind of guy, or does he like generalizations?
The faster a computer can calculate long division problems, the higher the overall performance of long division calculation
. Now THAT'S true.
