What is the impact of coupling and cohesion on software performance?

Coupling refers to how closely connected different modules are, while cohesion measures how well the elements within a module work together. High cohesion and low coupling generally lead to better performance.

Can you explain why high cohesion is beneficial?

High cohesion means that a module's components are closely related, which makes it easier to understand, maintain, and reuse. This can lead to improved performance as changes in one module are less likely to affect others.

What about low coupling? Why is it important?

Low coupling minimizes dependencies between modules, allowing them to be developed, tested, and updated independently. This isolation can enhance performance by reducing the risk of cascading failures.

Are there any trade-offs to consider?

Yes, while aiming for high cohesion and low coupling is ideal, it can sometimes lead to increased complexity in design. Balancing these factors is crucial for optimal performance.
