10 course recommendations on performance

We know that this interface Cloneable exists in Java. Classes that implement this interface will have the ability to be copied. At the same time, copying is performed in memory. In terms of performance, it is faster than directly generating objects through new, especially in In the generation of large objects, the performance improvement is very obvious. However, we know that copy is divided into deep copy and shallow copy, but shallow copy has the problem of incomplete copy of object attributes. For information about deep copy and shallow copy, please refer here: Gradual analysis of shallow copy and deep copy in Java 1. Shallow copy problem Let’s first look at the following code: public class Person implementations Cloneable{ /** Name **/&nb

Introduction: renqi: renqi Comparison of include and require in php: There is no big difference in performance between php's require() and include(). The only differences are that: the file is read and evaluated every time when include() is executed; the file is only processed once when require() is executed (in effect, the file content replaces the require() statement). That is, if there is code that contains one of these instructions and code that may be executed multiple times, it is more efficient to use require(). In addition, if you need to read a different file each time the code is executed, or there is a loop that iterates through a set of files,
