java - 第一次连接到 Glassfish v3 很慢

Question

第一次尝试从 swing 应用程序连接到 glassfish v3 时，速度非常慢。需要 4-10 秒。 在客户端:

public void myMethod(){
    NewSessionBeanRemote facade;
    try {
        InitialContext ic = new InitialContext();
        facade = (NewSessionBeanRemote) ic.lookup(NewSessionBeanRemote.class.getName());
        target.setText(facade.businessMethod());
    } catch (NamingException ex) {
        ex.printStackTrace();
    }
}

在服务器端:

@Stateless
public class NewSessionBean implements NewSessionBeanRemote {

    @Override
    public String businessMethod() {
        return String.valueOf(Math.random() + 121 + 300);
    }
}

@Remote
public interface NewSessionBeanRemote {

    String businessMethod();

}

我需要改变什么环境？

Answer 1

When trying to connect to glassfish v3 from swing application it is very slow for the first time.

可能是由于 lazy initialization of Application Server services (EJB 容器、连接池...)。

Takes 4-10 seconds.

后续调用呢？
