You will see this line when you use the top command:What are the meanings of each of these values?Asked this question today, I found that the answer is not very clear. Sure enough, every day with the most top command has not been well-acquainted ... Ashamed... So I looked up some information:Official explanationThe CPU (s) represents the CPU information. The meaning of each value is:Us:user

Basis of judgment:A physically encapsulated CPU (judged by physical ID) can have multiple cores (differentiated by Core ID).Each core can have multiple logical CPUs (judged by processor).One core implements this core's own hyper-Threading technology through multiple logical CPUs.The CPU cores entry contains the number of cores in the same physical package.The siblings entry lists the number of logical proce

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

The overclocking of the computer is to improve the working frequency of the CPU, graphics and other hardware by artificial way, so that they work stably under the rated frequency state. The Intel P4C 2.4GHz CPU For example, its rated operating frequency is 2.4GHz, if the operating frequency to 2.6GHz, the system can still run stably, then the overclocking was successful. The main purpose of

I. Preface in order to understand the meaning of this article more conveniently, it is better to look at the following cumbersome concepts and make it easier to understand. Do not understand these concepts, even after reading you can only know, run the next vmstat, look at the results of Linux feedback, but also to know why ~ First said the concept of memory. It's not about the CPU. Because the memory will consume

Choose 533 or 667? Detailed description of the relationship between CPU and memory I recently read some questions from some netizens about CPU, such as the gap between front-end bus 533 and 667, and how about the memory of ddrii667 on t2050 (Front-End bus 533 MHz ?...... I want to write thisArticleSo that more friends can understand this layer-by-layer relationship and know how to choose

A computer overclock increases the operating frequency of CPU, video card, and other hardware manually so that they can work stably at a higher rate than its rated frequency. Taking intel p4c 2.4ghz CPU as an example, its rated operating frequency is 2.4 GHz. If the operating frequency is increased to 2.6 GHz, the system can still run stably, and the overclocking is successful. The main purpose of

Linux performance monitoring, the following are the Vpsee common tools: Simple Introduction to Tools Top view process activity status and some system conditions Vmstat View system status, hardware and system information, etc. Iostat View CPU load, hard drive status SAR integrated tools to view system conditions Mpstat View Multi-processor status Netstat View network conditions Iptraf Real-time Network condition monitoring Tcpdump Crawl network packet,

To buy a dual-core computer, you must first understand the dual core. Look at Intel and AMD's respective dual-core, we focus on learning their differences, only after understanding to know, choose which is better, or more cost-effective. To be correct, the use of Intel and AMD's caching is not the same, and can not be directly compared to the version of the cache is wrong. The AMD L1 cache is not comparable to the L2 cache and the Intel L1 cache L2 Cache size, so don't be promiscuous. Intel's

Comparison of interrupt mode and polling mode Basic concepts of interrupts program interruption is usually referred to as interruption, refers to the CPU in the process of normal operation, due to pre-selection arrangements or the occurrence of various random internal or external events, so that the CPU interrupts the running program, and go to the corresponding service program to deal with, this process is

Loadaverage is displayed when we use the top command to view system resource usage, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the relationship between it and cpu utilization? When we use the top command to view the system resource usage, we will see the load average, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the rel

I tried to detect Keyboard Events in python by placing a function event. get () in pygame IN THE while loop. The result is that the cpu usage is always 100%. However, the event listening functions in the operating system and other languages (such as C #) basically do not occupy the cpu. How do they do this? Does it sacrifice the real-time response of events? I tried to detect Keyboard Events in python by pl

General CPU failure has the following: thermal failure, restart failure, black screen fault and overclocking failure (CPU go to die, of course, do not forget) 　One, the CPU pin contact is bad, cause the machine can not start General performance in a sudden unable to boot, the screen shows no signal output, excluding video card, monitor no problem, unplug 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

For the majority of computer users, CPU cooling is a top priority, whether it is the CPU produced by Intel or AMD, cooling the CPU is very important. Mainstream processors consume a lot of power and generate high heat. In this way, the CPU cooling requirements are more stringent. With the launch of the more powerful Pe

Understanding cpu system load in Linux 1. View System Load If your computer is slow, you may want to check whether it is too heavy. In Linux, we generally use the uptime command to view (w command and top command ). (They also apply to Apple's Mac computers .) If you type uptime in the terminal window, the system will return a line of information. The second half of this line shows "load average", which means "average system load". There are three nu

Two years ago, Microsoft's Asian Research Institute published the book "The beauty of programming". Chapter 1 section Section 1 "let you know the CPU usage curve, it can be said that it has set off a game-to-CPU usage curve nationwide. I am even thinking about how to handle the CPU usage curve while taking the bus. The book provides such a refreshing figure, attr
