Suppose you are going to publish an ASP program that is expected to be used by 1000 of users.

You are wondering whether two users can accurately reflect the compression capability of your program. Of course you can use standard test methods (publish your program and expect the best result

In our last article, we talked about the modeling method for the performance test load model when it landed, and here we start with the first and most commonly used method:Raw Data analysis methodBusiness scenario modeling is mainly about how users use the system, so it is the most effective and accurate method to analyze and model the original data used by the system, i.e. log. The so-called log refers to
