Difference between Performance Testing and Load Testing
Performance Testing:
Performance Testing is a type of software testing that is carried out to determine system performance in terms of sensitivity, reactivity and stability under a particular workload.
Load Testing:
Load Testing is a type of software testing which determines the performance of a system, software product or software application under real life based load conditions.
Difference between Performance Testing and Load Testing:
| Performance Testing | Load Testing |
|---|---|
| Performance testing is the process of determining the system’s performance that includes speed, reliability under varying load . | Load testing is the process of determination of behavior of system when multiple users access it at the same time. |
| In performance the load on which system is tested is normal. | In load testing peak load is used for testing. |
| It checks the behavior of the system under normal load. | It checks the behavior of the system under extreme load. |
| In performance testing, limit of load is both below and above the threshold of a break. | In load testing, limit of load is the threshold of a break. |
| It validates that the performance of system is proper. | It determines the operating capacity of the system or software application. |
| Speed, scalability, stability and reliability are tested during performance testing. | Only sustainability of the system is tested during load testing. |
| Performance testing tools are less costly. | Load testing tools are high costly. |
