Performance optimization in software development is a very important issue for programmers . A small problem can become a bottleneck for a large system. But it is very difficult for programmers to optimize their code by themselves. Fortunately, there are some great tools that can help programmers with code analysis and performance testing, making it much easier for programmers to optimize their code perform

the coding specifications, evaluate the code quality based on a certain quality model, and generate a system call relationship diagram; different from static testing tools, dynamic testing tools generally use plug-ins to insert some monitoring code into the executable file generated by the Code, used to count the data when the program is running. The biggest difference from static testing

During the maintenance of the application to the customer, I noticed some performance issues under high load. In theory, increasing the load on the application can degrade performance ratios. However, I think the rate of performance degradation is much higher than the load. I also found that performance can be improved by changing the logic of the application, or even reaching the limit. In order to understand this in more detail, we need to do some performance
