Add:

1, pressure and performance testing should be put on the product before the launch, rather than on-line after;
2, the test concurrency should be gradually increased by the small, such as 100 when observing the site load is how much, open the page is fluent, concurrency 200 is how much, the website is slow when the concurrency is how much, the site is not open when concurrency is how much;
3, a more detailed test of a page, such as e-commerce website can focus on testing shopping carts, promotional pages, etc., because these pages accounted for the overall site visits a large proportion.

Note: Webbench do stress and performance testing, the software itself will also consume CPU and memory resources, in order to test the accuracy, it is recommended to install Webbench on other servers, has reached the test data more accurate.
