| Load test | Performance test |
| Load test helps to understand how scalable the system is. | Performance testing aims to understand the response time of application. |
| It is performed to ascertain how the components of a system are performing under a given situation. | It is used to test the system constantly and steadily by increasing the load on the system till the time it reaches the threshold limit. |
| The resource usage,scalability and the reliability of the product are validated here. | It is used to assign the system the largest job to handle the endurance and monitoring the results. |
| It is a subset of the performance engineering. | It is also called as volume testing and endurance testing. |
