Pooling is not a new technology, it is more like a software design pattern, the main function is to cache a set of initialized objects, ready to use. In most scenarios, the object pool caches objects that are too expensive to create or need to be repeatedly created and used. The time ...
Use object pooling to increase the speed and performance of Java applications, and reduce memory use
Object pooling is a simple and elegant way to conserve memory and enhance speed in Java applications. By sharing and reusing objects, processes (threads) aren’t bogged down by the instantiation and loading time of new objects, or the overhead of excessive garbage collection....
With these two interfaces that defines our API for object pool pattern, we can implement an abstract class to define the logic for object pooling. package com.admfactory; import java.util.concurrent.BlockingQueue; import java.util.concurrent.LinkedBlockingQueue; public abstract class ObjectPool imple...
Java BasePooledObjectFactory 对象池化技术 使用GenericObjectPool只需要创建一个对象工厂类,继承BasePooledObjectFactory并重写它的create()和destroyObject()。 如下文中的:SftpPool.java public interface PooledObjectFactory<T> { /** * 创建一个可由池提供服务的实例,并将其封装在由池管理的PooledObj...
In this post we will take a look at how we can create an object pool in Java. In recent years, the performance of the JVM has multiplied manifold that object pooling for better performance has been made almost redundant for most type of objects. In essence, creation of objects are no lo...

Object pooling can offer a significant performance boost; it is most effective in situations where the cost of initializing a class instance is high, the rate of instantiation of a class is high, and the number of instantiations in use at any one time is low. ...
This chapter describes object pooling, a solution to potential limited-resource issues, including bottlenecks that occur when there are not enough resources to meet clients' demands. The following topics are included in this chapter: Introduction to Object Pooling Process Overview for Object Pooling...
