Now, in addition to new jobs, I have basically been dealing with servers, and it takes a short time to develop front-end services.
Currently, the company's performance monitoring and testing: Xhprof and AB testing
Xhprof-facebook's open-source, lightweight PHP performance analysis tool: includes the number of function calls, the time spent (the time spent and the time spent on including internal functions), the memory/CPU occupied, peak memory usage and percentage
For details about how to install and use it, you can go to Baidu. This is really cool and easy to use. You can quickly know the function of the file where the performance bottleneck is located, and then perform targeted optimization: for a specific description of the Database, check the source code, and even have a connected Table query, and then put the query into foreach, resulting in many small queries. Next we will have targeted optimization.
