Why Scalability Testing Must Be Experience-Led

An application can handle thousands of requests without errors and still deliver a poor user experience. This gap often goes unnoticed when scalability testing focuses on how much traffic a system can handle rather than how well it performs under that traffic. For example, a shopping application may process every request successfully as traffic grows. But if the application takes longer to retrieve product details or check stock availability, users may wait longer to search for products, update their carts, or complete checkout.
