be a bit higher and more persuasive than the Apache AB accuracy rate.qpt-the number of users per second and response time, per connection response to user times.The result of the test is mainly to look at these two values. Of course, only these two indicators do not complete the analysis of performance, we also need to the server's The CPU, the men carries on the analysis, can draw the conclusion Second, Webbench Webbench is a Web site stress

1.
