Performance Testing vs. Load Testing: Key Differences

Feature	Performance Testing	Load Testing
Definition	A broad category of testing that evaluates a system's overall performance and behavior under various conditions.	A specific type of performance testing focuses on how the system behaves under increasing user loads.
Objective	Assess the system's overall responsiveness, stability, resource usage, scalability, and adherence to performance requirements.	Determine the system's capacity and identify performance bottlenecks under increasing user loads.
Scope	Covers a wide range of performance aspects, including response time, throughput, resource utilization, error rates, and scalability.	Primarily focuses on response time, throughput, and scalability under different load levels.
Test types	Includes load testing, stress testing, endurance testing, spike testing, and more.	Primarily load testing, but it may also incorporate elements of stress testing.
Test load	Varies depending on the specific test types and performance goals.	Gradually increases the load, sometimes exceeding expected levels to identify breaking points.
Tools used	Performance testing tools, monitoring tools, load testing tools, stress testing tools.	Load testing tools, monitoring tools, and traffic generators.
Expected outcome	Understand the system's overall performance characteristics and identify areas for improvement.	Define the system's load capacity and identify potential bottlenecks to ensure scalability and resilience.
Risk Mitigation	Aids in mitigating performance risks by identifying and addressing potential performance bottlenecks and scalability limitations before deployment, ensuring the application can handle expected user loads and maintain acceptable performance levels.	Aids in mitigating risks associated with system failure or performance degradation under load by identifying critical failure points, stability issues, and potential system vulnerabilities, enabling improvements to enhance system reliability and resilience under stress.
GoodFirms Note	Load testing is a subset of performance testing, focusing on specific aspects of performance under load	Performance testing provides a broader picture of system behavior, while load testing reveals limitations under increasing user activity.
