application performance testing tools

PHP simple performance testing tools I. Overview nbsp; this class mainly detects the running time of a piece of code and some PHP efficiency problems. II. usage first, The require class mainly uses the interfaces begin (), preTime () and end () begin ($ output, $ environment) to detect the initial position, when this interface is executed, the detection starts.

Use Chrome to access the site you're testing, and navigate to the page where you want to test the action or the previous page of the page being tested.

Diagnosing database performance problems as doctors diagnose patients, it is necessary to combine their own accumulated experience and rely on scientific diagnostic reports to determine exactly where the source of the problem is. In the previous three articles we introduced many methods to optimize database performance, although it is important to master the optimization skills, but the diagnosis database

The susseed returned by its result does not mean that the request was successful, such as:Enter a non-existent website, the result is still have 479 susceed4, the actual testing process, we can only go to the log to see if the server received so many requests. You can allow development to insert a flag in the code, as long as the access is succe

This is also a benchmark for "Evaluating Performance Verification" and a benchmark for testing termination. In this case, the goal is to set 30 concurrent users in the
