cpu resources

SQL Server Cpu 100% is not very common. It generally causes performance problems, such as blocking, connections, and I/O disks. Therefore, the usage of SQL Server is generally low. However, in some cases, the Cpu usage is 100%. What operations does

This article gives you a detailed description of the network disconnection problem caused by ARP detection on the vro. I believe you have read this article to learn about route settings. LAN networks are easy to use, but it is not easy to manage.

INFORMIX databases are widely used relational databases. How to improve their application performance is a matter of concern. Especially with the increasing volume of data in databases and the increasing volume of transactions processed by

This article is based on Zhou Zhiming's "in-depth understanding of Java virtual machines"If the collection algorithm is the method of memory recycling, the garbage collector is the specific implementation of memory recycling. There is no provision

Linux under the W command to see the system load:The first line of the command results shows the three numbers after load average meaning:1 minutes, 5 minutes, 15 minutes, the average number of processes per unit time using CPU resources, the larger

Original link: Spark Streaming performance tuning　The Spark streaming provides an efficient and convenient streaming mode, but in some scenarios the default configuration is not optimal, and even the external data cannot be processed in real time,

The most common method for setting automatic service startup is in rc. add a script similar to the following in local: # sshd/usr/local/sbin/sshd # proftpd/usr/local/sbin/proftpd # apache/home/apache/bin/apachectlstart #

Concurrent running of computer programs is a frequently discussed topic. today I want to discuss various concurrency methods in Python. Concurrent running of computer programs is a frequently discussed topic. today I want to discuss various

Nic binding to a single kernel process and asynchronous I/O should be able to achieve optimal communication performance, but in reality, we often find that this mode does not achieve the expected results, this may be because the NIC is competing for

Today we will study Java virtual machines using garbage collection algorithms and common garbage collectors. The program counters, virtual machine stacks, and local method stacks of the Java Virtual Machine memory area are 3 regions that are born

JavaSE -- thread synchronization, javase thread Why is thread synchronization required?Synchronization is to work in a coordinated pace and run in a predetermined order. For example, if you have finished speaking, I will not talk about it together.

1. Thread Life cycleA thread is a process that executes dynamically, and it also has a process from generation to death.(1) Five states of the life cycleNew (new Thread)When an instance (object) of the thread class is created, the thread enters a

First, the origin of demandWeb-server usually have a configuration, the maximum number of worker threads , the backend service generally has a configuration, the number of threads in the worker thread pool, the number of threads configured by

One, the difference between the thread and the process:The internal data and state of multiple processes are completely independent, and multithreading is a shared piece of memory space and a set of system resources that may interact with each other.

Static methods in the thread classThe static method in the thread class represents the thread of the operation that is executing the thread of the code block where the static method resides . Why there is a static method in the thread class so that

A mention of multithreading in general everyone's first feeling is that you can improve the program performance, in the actual operation often encountered performance problems, are trying to use multi-threaded to solve the problem, but the
