Technical 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 and destroyed, especially the resource-intensive object creation and des

3.6 Connection Pool Similar to Microsoft's previous data access technology, ADO. NET includes built-in support for connection pooling. 3.6.1 Connection handle and physical connection If you are using Visual Studio, you can use the Visual Studio debugging tools to examine some of the object's internal private properties. For example, write some code to open a SqlConnection and set a breakpoint where the Open method is called. Right-click the object in

If you feel helpful, share it with your friends and thank you for your support. This article demonstrates the use of buffered channels to implement a resource pool, which ca

Basic working principle of connection pool 1 , basic concepts and principlesAs 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 relea

Use connection pool Let's take a look at the sqlconnection string parameters of ado.net. We have set the maximum and minimum pools. How can we see the differences between Windows app and web appp? We can create a web application or Windows app. After the app is enabled, you can use sp_who2 in the SQL analyzer to view the connected client, obviously, if a web application or Windows app starts n connections each time a client starts, it is much larger

the program that require a lot of threading to handle tasks, then if you're going to create threading in the same way , then the performance of the system will be very bad, let alone in memory-constrained mobile devices, the main impact is as follows:1、线程的创建和销毁都需要时间，当有大量的线程创建和销毁时，那么这些时间的消耗则比较明显，将导致性能上的缺失2、大量的线程创建、执行和销毁是非常耗cpu和内存的，这样将直接影响系统的吞吐量，导致性能急剧下降，如果内存资源占用的比较多，还很可能造成OOM3、大量的线程的创建和销毁很容易导致GC频繁的执行，从而发生内存抖动现象，而发生了内存抖动，对于移动端来说，最大的影响就是造成界面卡顿The solution to the problem described above is to reuse

Pool technology can significantly optimize the performance of server applications, improve program execution efficiency and reduce system resource overhead. The pool described here is a generalized pool, such as database connection pool, thread pool, memory

threads does not greatly improve the efficiency of the program "1". Therefore, when dealing with concurrency problems with Python, try to use multiple processes rather than multithreading. In concurrent programming, the simplest pattern is that the main process waits for the task and launches a new process to handle the current task when a new task arrives. This is how each task is handled by one process, each processing task is accompanied by the creation, operation, and destruction of a proce

Java Multithreading Series--"Juc thread pool" 04 thread pool principle (iii)This chapter describes the life cycle of the thread pool. In the Java Multithreading Series-Basic concepts of 01, we've introduced threads in 5 states: New state, ready state, running state, blocking state, dead state. The thread pool also has

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

By recycling application pool settings, you can control how system resources are recovered. The following sections describe how to specify a recycle application pool setting. Specify Recycle application pool settings The Recycle application pool settings are specified in the Recycle tab of the application pool's

I went to the interview today and met a question about the database connection pool, which is clearly something that is often used. But after I shut down my computer and book, I found many things I still cannot tell clearly, I have specially reproduced this article to supplement it. Basic working principle of Connection Pool 1. Basic Concepts and Principles From the above analysis, we can see that the root

Implementation of simple thread pool in Linux Technical Background of Thread Pool In object-oriented programming, it takes a lot of time to create and destroy objects, because creating an object requires obtaining memory resources or other resources. Even more so in Java, virtual machines will try to track every object so that garbage collection can be performed after the object is destroyed. Therefore, one

Basic use of Java Thread Pool Threads play an important role in both Java Development and Android development. Today we will talk about the thread pool. I. Thread Pool Overview In Android development, we often put a time-consuming task in a thread for execution to avoid ANR exceptions. However, if we enable multithreading on a page and the thread finishes execu
