Object caching and pooling: the application server automatically pools stateless session beans at the server level, reducing the amount of time spent in object creation and garbage collection.
对象高速缓存和合用：应用程序服务器自动在服务器级合用无状态会话bean，这减少了花在对象创建和垃圾收集上的时间。
The get-use-close model might sound inefficient, but the connection pooling the application server implements should make the "get" operation cheap.
get - use - close模式看起来效率不高，但是应用服务器实现的连接池可降低“获得”操作的成本。
Generally, it is not possible for applications running on an application server because these applications use connection pooling so that connections are not personalized.
通常，这对于在应用服务器上运行的应用程序是不可能的，因为这些应用程序使用连接池，连接不是个人化的。
