Object pools are used to restrict the number of instances of a certain class.
使用对象池限制特定类的实例的数量。
Apart from implementation details, object pools generally have the interface illustrated in Listing 1.
如果不考虑实现细节，对象池一般采用清单1所示的接口。
Run time: performance degradation (even when using object pools), both in response time and CPU consumption, is evident with complex nested objects.
运行时：在响应时间和CPU的消耗两者上性能的下降(即使当使用对象池时)，明显有着复杂嵌套对象。
To tune performance when using concurrent message delivery, we must turn our attention to a number of object pools managed by the application server.
为了在使用并发消息传递时优化性能，我们必须将注意力转向应用程序服务器托管的许多对象池。
WebSphere Application Server also supports the general concept of object pools, with each pool consisting of a pool manager providing access to pools for different class types.
WebSphereApplicationServer还支持对象池的常规概念，每个对象池均具有池管理器，从而为不同类类型提供对象池访问。
This enables accessor factory implementations to store the accessor factories in object pools to achieve better performance (due to less initialization overhead and less garbage collection).
这就允许访问器工厂实现将访问器工厂存储在对象池中，以实现更好的性能(因为初始化开销更少，垃圾回收工作也更少)。
Click the expand icon to the left of the MBLOG option to show the different object types in the database (Buffer Pools, Groups, and so on).
单击MBLOG选项左边的展开按钮显示数据库中的不同对象类型(BufferPools和Groups等等)。
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。
