字节或国际？哪一个通过套接字发送更快？

Question

我正在编写一个应用程序,旨在集中在mysql数据库中生成的与项目管理相关的所有数据.该应用程序可分为3个部分/项目,如下所示:

• 服务器层:

充当多个客户端之间的层并保持连接到数据库(mysql).它侦听协议类,然后执行INSERT,UPDATE,DELETE,SELECT等操作.它是用普通的java 2SE而不是2EE编写的,因为它是一个非常简单的类,可以独立于服务器.

• 通讯协议:

一个扩展java.util.EventObject并实现Serializable接口的类.它用于存储与客户端和服务器之间的通用协议相关的信息.这是实际上通过套接字"传播"的类,因为它的工作类似于协议.

• 客户申请:

基本上是gui.它是用javafx 2.1编写的,旨在提供一个漂亮的美容界面来收集信息.

我的问题是,为了通过代码提高可读性,我在通信协议类上创建了一些静态最终字段,然后将其声明为int,我想知道使用byte是否可以改进代码,因为(再次)它将通过一个套接字.我知道JVM会将等效空间分隔为字节,短路和整数变量,但是通过套接字发送数据时会出现这种情况吗？所以,在这种情况下,哪一个更好:

/**
 * 
 */
private static final long serialVersionUID = 7530533341506425480L;


public static final int CLIENT_DISCONNECTED = -1;
public static final int NEW_INFO_INSERTED = 0;
public static final int SHUTDOWN_ORDER = 1;

public static final int INFO_NOT_INSERTED = 100;

public static final int CLIENT_CONNECT = 10000;
public static final int CLIENT_LOGIN = 10001;

public static final int SERVER_LOGIN_OK = 20001;
public static final int SERVER_LOGIN_FAILED = 20002;
public static final int SERVER_SAYS = 20003;
public static final int SERVER_IMAGE_INSERTED = 20004;

public final static int DB_WORKERS = 1001;
public final static int DB_PROJECTS = 1002;
public final static int DB_SECTORS = 1003;
public final static int DB_ACTIVITIES = 1004;
public final static int DB_SUBACTIVITIES = 1005;
public final static int DB_INSERTION = 1006;
public final static int DB_REL_COST = 1007;
public final static int DB_FUNCTIONS = 1008;
public final static int DB_INSERTION_ID = 1009;
public final static int DB_INSERTION_IMG = 1010;

public final static int DB_WORKER_INSERTED = 4010;
public final static int DB_ACTIVITY_INSERTED = 4011;
public final static int DB_SECTOR_INSERTED = 4012;
public final static int DB_SUBACTIVITY_INSERTED = 4013;
public final static int DB_FUNCTION_INSERTED = 4014;
public final static int DB_IMAGE_INSERTED = 4015;
public final static int DB_PARENTS_INSERTED = 4016;

还是用字节？干杯

Answer 1

正如ColeJohnson所说,字节小于整数,因此技术上发送速度更快.但是,除非您一次发送100千或数百万这些值,否则尺寸差异无关紧要.
