Users need to connect to the speed of Web site according to the Internet and transform the way that they may be dial-up or broadband Internet right to use. When downloading a program, the user can wait a long time, but if only to see a page would not have. If the reply time of a web site is too long (for example, more than 5 seconds), then the user will not have the endurance to wait for left. In addition, some pages are out of the restrictions, if the response is too slow, the user may not have time browsing content, you need to re-land. Moreover, the connection speed is too slow, but also may cause data loss, allowing users to not get the real page.

Web load test is to measure the system at a load level of performance to ensure that within the requirements of Web systems to work properly. Load level can be at some point in the same time, the number of users to access Web Systems may also be a number of online data processing. For example: Web application system that would allow the number of simultaneous users online? If more than this amount, what will the phenomenon? Web application system is capable of handling large numbers of users on the same page request?

Load testing Web systems should be scheduled for release later in the actual network environment for testing. Because an internal staff, in particular, the project team is always limited, and a Web system can also handle the number of requests will go far beyond this limit, therefore, only on the Internet, to accept the load test, the result is the right credible. Stress testing is the actual destruction of a Web application system, test system reflected. Stress testing is to test the system constraints and fault resilience, that is, Web application testing system will not collapse, under what circumstances would collapse. Hackers are often the wrong data load until the Web application system crash, and then when the system is restarted to obtain access.
