Small groups appear to perform better when it comes to

Making decisions quickly.

Explanation:

Small groups perform better when decisions need to be made. This is because as the number of members is small, the number of different opinions is also smaller. This makes it easier for members to talk about their opinions and reach a decision faster. In a large group, the number of opinions would be higher relative to the size of members, as a result, much more time would be spent discussing all opinions and reaching a concrete conclusion.
