Basic working principle of connection pool 1. Basic concepts and principles As can be seen from the above analysis, the root of the problem lies in the inefficient management of the database connection resources. We know that for shared resources, there is a well-known design pattern: resource pools (Resource pool). The pattern is to solve the problem of the frequent distribution of resources and the releas

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

Introduction C/C ++ memory management is a headache for almost every programmer. allocate enough memory, track the memory allocation, and release the memory when it is not needed-this task is quite complicated. The direct use of the system to call malloc/free and new/delete for memory allocation and release has the following drawbacks: When calling malloc/new, the system needs to find an idle memory in the memory idle block table based on "first match", "Optimal Match", or other algorithms, an

I. The question arisesNetwork requests usually have two scenarios: the first, the request is not very frequent, and each connection will remain for a considerable period of time to read data or write data, and finally disconnected, such as file download, network streaming media. The second is frequent requests, but the connection is disconnected after a small amount of data is read/written.Given the concurrency of the service, if each request comes in after the service starts a thread for it, th

Sun in the JAVA5, the Java thread of the class library to do a lot of expansion, in which the thread pool is one of the new features of JAVA5, in addition to the thread pool, there are many multi-threaded related content, for multi-threaded programming has brought great convenience. In order to write high-performance and stable and reliable multithreaded programs, the new content of the thread part is parti

Summary: The connection pool can improve database access performance to a certain extent. This article discusses what is a connection pool, how it improves database access performance, and how. NetCreate a connection pool and add or remove connections. Introduction Connecting to a database is an applicationProgramBut they are crucial.

Record the process of learning the thread pool, the function that the code uses boils down To:Pthread_mutex_lockPthread_mutex_unlockPthread_cond_waitPthread_cond_signalPthread_cond_broadcastPthread_createPthread_joinThe program also uses a linked list,There is also a knowledge point: any type of data can be of type void,however, the type of void must be cast before it is Used./**author:greens_ren*description: thread

1. IntroductionThe 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 threads. Threads are scarce resources that, if created indefi

# Process Pool # Why do you have a process pool? #在程序实际处理任务过程中, there are thousands of tasks that need to be performed when busy, and there may be sporadic tasks at leisure. #那么在成千上万个任务需要执行的时候, do we need to create thousands of processes? #首先, creating a process consumes time, The destruction process also consumes time. Second, even if thousands of processes are turned on, the operating system does not a

In the previous article, we created a thread when we used the thread, so it was easy to implement, but there was a problem: If you have a large number of concurrent threads, and each thread is finished with a short task, creating a thread frequently can greatly reduce the efficiency of the system because it takes time to create threads and destroy threads frequently. So is there a way to make threads reusable, to perform one task, not to be destroyed, and to continue to perform other tasks. In J

Simply put, if an application needs to create and destroy threads frequently, and the task executes in a very sho

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.

A company websiteProgramAfter a long period of operation, the speed slows down, and the speed becomes faster after the website is restarted. It is estimated that the memory and CPU resources occupied by the website program are not released in time, so the website needs to be restarted to release resources at intervals. However, manual restart does not always solve the problem. How can we achieve automatic management? Iis6.0's application pool automati
