Performance overviewWhy is the program always so slow? What the hell is it doing now? Where did all the time go? Perhaps, you often complain about these problems. If so, it means you have a performance problem with your program. Performance problems in some cases, compared to functional problems, may not be much of a problem, just for a moment, it's gone! However

[Java Performance] Performance of threads and synchronization-thread pool/ThreadPoolExecutors/ForkJoinPoolThread Pool and ThreadPoolExecutors Although the Thread type can be directly used in the program for Thread operations, the Thread pool is used, especially on the Java EE application server, generally, several thread pools are used to process requests from the client. The support for thread pools in Jav
