性能测试和负载测试的区别

性能测试：
性能测试是一种软件测试，用于确定系统在特定工作负载下的灵敏度、反应性和稳定性方面的性能。

负载测试：
负载测试是一种软件测试，它确定系统、软件产品或软件应用程序在基于现实生活的负载条件下的性能。

性能测试和负载测试的区别：

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.
