Http://teamojiao.iteye.com/blog/456851 I recently came into contact with the connection pool and Object pool technology in the optimization of an internal test tool class. I changed the original database access operations not using the connection pool to the connection pool

1. Small integer Object poolIntegers are used extensively in programs, and in order to optimize speed, Python uses a small integer pool of objects to avoid frequent application and destruction of memory space for integers.Python defines small integers as [-5, 256] These integer objects are set up well in advance and are not garbage collected. In a Python program, all integers that are in this range use the

Servlet thread pool and EJB object pool 2008/11/13 p.m. go to http://hi.baidu.com/%D3%C0%CA%C0%CF%E9%BA%CD/blog/item/ca83e8876c55142dc65cc31a.html Currently, all B/S system applications can be classified into statefull and stateless. Stateful means that some information should be retained throughout the processing of the system, while stateless means that, on

Object pool technology can avoidProgramCreates and deletes a large number of objects in the lifecycle. If you know that the program requires a large number of objects of the same type and the object's life cycle is very short, you can create a pool for these objects for caching. The most difficult aspect of Object

Using Object pools Joa EbertIs right when he says that utilizing object pools can make your codePerform a lot faster. An object pool is just a container for a bunchPre-constructed objects that are kept in memory ready for use, ratherThan being repeatedly allocated and destroyed on demand.

1. Why does it take a lot of time to create and initialize new objects using the object pool technology. In the initialization of such objects, if you rely on rpc Remote calls to create objects, such as connecting to remote service resources through socket or http, the most typical is the database service and RemoteQueue ), establish a connection 1. Why does it take a lot of time to create and initialize ne

or when memory is not sufficient, Automatically reclaims the memory occupied by garbage objects. There are always pros and cons, although it provides great convenience for Java programmers, but it also brings a large performance overhead. This overhead includes two aspects, first, the object management overhead, in order for the GC to properly dispose of the object, it must monitor the running state of eac

Jakarta Object pool ☆Why use Object pool?The appropriate use of object Pooling technology can effectively reduce the consumption during object generation and initialization, and improve the system operation efficiency. The Jakarta

Apache Commons-pool is essentially an "object pool" that maintains a container of object collections through certain rules; Commos-pool in many scenarios, to implement "connection pooling"/"task worker pool" and so on, everyone co

The Singleton mode limits only one instance for a class, and the object Pool Mode limits the number of class instances. The object pool class is like an object administrator. It stores instances of classes with a limited number of instances in the form of a static list (that

The basic idea of using the object pool is to save the used objects and use them again when this object is needed for the next time, this reduces the overhead caused by frequent object creation to some extent. Not all objects are suitable for pooling-because maintaining the object
