Regarding performance tuning, let me first talk about my feelings. Java performance tuning is not like learning a programming language, which cannot be mastered and applied through straight-line thinking. It has high requirements for the breadth and depth of engineers' technology.
In the Internet age, a simple system includes applications, databases, containers, operating systems, networks and other technologies. Once performance problems occur online, you may need to coordinate multiple components to optimize. This is the breadth of technology; and many The performance problem is hidden deeply. It may be because of a small code, or because of the wrong type of thread pool. In the final analysis, what is tested is our understanding of this technology. This is the depth of technology!
