About CPU Cache--The program apes need to know. This article will describe some of the CPU cache related knowledge that a program ape or it practitioner should know Article welcome reprint, but reproduced when please retain this paragraph text, and placed on the top of the articleLu Junyi (Cenalulu)This text address: http://cenalulu.github.io/linux/all-about-

first, processor CPU knowledge Classification of ①CPU CPU brands have two camps, respectively, Intel (Intel) and AMD, the two industry bosses almost monopolize the CPU market, we take apart the computer to see, but also Intel and AMD brand (of course, not excluding the extremely small cottage of the

Thread affinity why requires CPU affinity of threadsThe application is executed in multi-threaded way, most of the time the thread can be reasonably dispatched. In some cases, however, an important thread is paused, and the time slice is assigned to a thread that is not important. When a thread pauses to hibernate and then wakes up, it needs to reload "cache line" (CPU L1/L2 cache). When a thread's working

Operating Win7 Pure version of the system encountered a sudden high CPU usage and suddenly become low, seriously slowing down the system running speed, but also led to computer fever, if a long time, the loss of computer hard disk is very large, why this situation? Many users do not know the CPU usage suddenly become high and suddenly lower reason, the following small series and you explain the Win7 system

CPU heat conduction silicone also known as thermal grease, different areas of the user name is also different in the computer City and online Mall we can easily buy the CPU thermal silica gel, according to good or bad, its price from a few yuan to dozens of yuan. The following article mainly with you to install the CPU or clean up the

Often feel that the system resources are not enough, a machine ran on less than 3 more important services, but every day we have to do a backup compression, such as processing, the network for a long time transmission, which is very influential in this is not enough to use the system resources;At this point, we can limit some of the less important things, such as copy/Backup/synchronization, to one CPU or one core of a multicore

What about computer processors? Below we will focus on how to look at the computer processor and how to look at the CPU is good or bad for everyone to do a deep introduction. How does the processor look? How to look at CPUs There are a lot of ways to look at the CPU, and it's very simple, the most straightforward way is to get into--My computer--right-click the mouse in the blank area--Properties You can

　What is CPU usage? CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. The higher the usage rate, the more your machine runs a lot of programs at this time, and less. The usage rate is directly related to the strength of your CPU.

Now people buy mobile phones, are more concerned about the use of what CPU, because the CPU directly determines the performance of the phone, the CPU on the phone is like a human brain, it is the entire mobile phone control system, is also the logical part of the control center. Also equivalent to the engine of the car, the more powerful the engine, the faster th

I like Oracle very much. I also like to sum up the experience and lessons on optimizing the CPU usage of Oracle in my work. Let's talk about this question in detail. CPU is one of the servers I like Oracle very much. I also like to sum up the experience and lessons on optimizing the CPU usage of Oracle in my work. Let's talk about this question in detail.

Other types and versions of the operating system configuration may vary, please refer to the appropriate operating system official documentation.If the CPU of ECS Linux system keeps running high, it will affect the stability of the system and the ope

In QEMU/KVM, QEMU provides a simulation of the CPU, showing a certain number of CPUs and CPU characteristics of the client, and in the case of KVM Open, the execution of CPU instruction in the client has the hardware processor's virtualization function to assist the execution, which is very effective.QEMU/KVM provides the client with a complete set of hardware sy

CPU as the heart of the computer, it starts from the computer to shut down all non-stop operation, maintenance of it is particularly important to facilitate the computer diligent work.1. Heat dissipation first. CPU work with the production of heat, heat dissipation can not be less, the CPU is 9ぷ 魑 LU 5~65℃, specific according to different

Multi-core CPU A central processor has two or more cores! Pretty Head, with two or more brains! However, the running speed is not double that of a single-core CPU, because a single-core CPU is 100% running, and a dual-core CPU is 60% multiplied by 2 running. It requires three cores, 50% multiplied by three cores, 40% m

During system maintenance, it may be necessary to review the CPU usage at any time, and to analyze the system condition according to the corresponding information. In CentOS, you can view CPU usage by using the top command. After running the top command, the CPU usage status is displayed in full-screen mode, and will be in the dialog-using top-based commands, you

Do not know if you have no sense, nearly one or two years of DIY hardware field, the CPU water-cooled radiator has a trend of increasing fire. Search on the Internet to know that, at present many manufacturers have launched a CPU water-cooled radiator, including the mainland manufacturers of the figure. CPU water-cooled Radiator Why has the fire come

We just know the CPU frequency, the core number, two cache and other parameters can be, the higher the frequency of high-frequency operation, the core number of the more the better, two-level cache the more about good. For graphics cards too, we just need to know the graphics card frequency memory and brand, the main frequency is also the speed of the graphics card, the higher the better, video memory is the display performance of the graphics card,

To solve the CPU usage is too high, first of all, we should understand what is the cause of high CPU, we mainly from the software and hardware to start with: 　　1, the software caused by the high CPU utilization rate This is mainly related to system problems, such as the system is too bloated, open too many programs and computer virus Trojan, etc. will

Cause the CPU temperature is too high: First, the ambient temperature Virtual CPU Especially in summer, CPU idle is its temperature can reach more than 50 degrees, full-speed work is more than 70, although this kind of temperature can be accepted in a short time, but if used for a long time, it will affect the life of the

CPU and memory are the most reasonable (both the CPU and memory have the corresponding speed and bandwidth. In the computer configuration process, the CPU speed and bandwidth are used together with the corresponding rate and bandwidth memory, which will directly affect the performance of the entire machine. Improper combination will often waste
