A company's web site program after a long run, slow speed, restart the site after the speed significantly faster, estimated that the Web site program occupied by the memory and CPU resources can not be released in time, only need to restart the site every time the release of resources. But manual restart is not the solution to the problem, how to achieve automatic management? The IIS6.0 application pool Automatic recycle feature solves this problem.An

Introduction?? This article will introduce the Chang and packing unpacking mechanism, the reason is that the two together introduced, is because many articles on the internet when it comes to Chang, the wrapper class cache mechanism, Java constant pool, mixed together in a discussion, or even completely the two as a whole, for beginners to bring a lot of trouble, I just came over. Also, because the caching of wrapper classes is the same as the idea of

1, for a asp.net database connection pool, you can configure a link pool as a link string using a set of name-value pairs. For example, you can configure whether the pool is valid (default is valid), the maximum and minimum capacity of the pool, and the time that the queued request for the link is blocked. The followin

The Memery pool technique is to apply a certain number of memory blocks that are equal in size (typically) to be reserved before actually using memory. When there is a new memory requirement, a portion of the memory block is separated from the memory pool, and if the memory block is not enough, then continue to request new memory. One notable advantage of this is that memory fragmentation is avoided as much

benefits of using a thread pool The rational use of the thread pool can bring three benefits. First: Reduce resource consumption. Reduce the consumption caused by thread creation and destruction by reusing the threads that have been created. Second: Improve response speed. When a task arrives, the task can be executed without the need to wait for the thread to be created. Third: Improve the manageability of

Source:Silenceduthttp://www.codeceo.com/article/java-threadpool-learn.htmlTechnical background of thread poolIn object-oriented programming, creating and destroying objects is time-consuming, because creating an object takes memory resources or more resources. More so in Java, virtual machines will attempt to track each object so that it can be garbage collected after the object is destroyed.So one way to improve the efficiency of the service process is to minimize the number of objects created

destroying threads than on the actual user requests. The active thread consumes system resources in addition to the overhead of creating and destroying threads. Creating too many threads in one JVM can cause the system to run out of memory or "switch over" due to excessive memory consumption. To prevent the lack of resources, the server application requires some means to limit the number of requests processed at any given time. The thread pool prov

1. For the ASP. NET database connection pool, you can use a group of name-value pairs to configure the connection pool as a link string. For example, you can configure whether the pool is valid (which is valid by default). The maximum and minimum capacity of the pool is used for the time when the queued requests that o

List of Reading Notes and articles Basic working principle of Connection Pool 1. Basic Concepts and Principles From the above analysis, we can see that the root cause of the problem is the inefficient management of database connection resources. We know that there is a well-known design pattern for shared resources: resource pools(ResourcePool ). Is this pattern designed to solve frequent resource allocation? Release issues. To solve the above problem

When the task is finished, the
