struts action 加载 代码顺序

Question

在action中:
public class ActionTest extends ActionSupport(){
private Service service;

private String name;
private String sex;

public String execute() throws Exception {
    return SUCCESS;
}
public String add() throws Exception {
    return "add";
}

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getSex() {
    return sex;
}
public void setSex(String sex) {
    this.sex = sex;
}

}

和

public class ActionTest extends ActionSupport(){
private Service service;

private String name;
private String sex;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getSex() {
    return sex;
}
public void setSex(String sex) {
    this.sex = sex;
}

public String add() throws Exception {
    return "add";
}

public String execute() throws Exception {
    return SUCCESS;
}

}
为什么都调用execute方法时 页面响应的时间会相差1秒多?和代码顺序有直接关系?求大神指点
