What does SAP recommend for performance testing in the "Test" phase?

SAP recommends performing load, stress, and performance tests in the "Test" phase to ensure system stability and responsiveness. This approach is vital because it validates how the system will behave under various conditions, particularly when subjected to heavy workloads or peak usage scenarios. By conducting these specific types of tests, organizations can identify potential bottlenecks, assess resource utilization, and ensure that their systems can handle expected user loads, which is essential for maintaining a robust and reliable application environment.

Load testing helps in understanding the maximum capacity of the system, while stress testing evaluates how the system responds when pushed beyond normal operational capacity. Performance testing overall is crucial for verifying that the system meets the required performance benchmarks and user expectations, thereby enhancing the user experience and minimizing downtime.

The other options do not comprehensively address critical aspects of performance testing, making them less suitable for ensuring the effectiveness of the system before going live.
