Can you tell about different types of testing aimed at evaluating system performance?

There are several main types of performance testing, each evaluating the system from different perspectives:

• Load Testing — checks how the system behaves under expected normal load.

• Stress Testing — determines the system's limits by applying load above normal to identify failure points.

• Soak Testing — tests the system's stability under load over an extended period to identify memory leaks and performance degradation.

• Spike Testing — assesses the system's response to sudden load spikes.

• Scalability Testing — examines how the system handles increased load and resources.

Each of these types helps identify bottlenecks and ensures the system will operate efficiently under real-world conditions.
