How can excessive polymorphism lead to performance issues?

Answer
Excessive polymorphism can increase method call overhead due to dynamic dispatch.
While polymorphism enhances flexibility, it introduces a slight overhead due to dynamic method dispatch at runtime. In scenarios with extensive polymorphic calls, such as tight loops or performance-critical sections, this overhead can accumulate, impacting performance. For instance, a large-scale system calling a method on thousands of polymorphic objects in a loop may experience slower execution compared to direct method calls.
