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.
