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 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.|
