We can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. There are six entries in the/proc/cpuinfo description for multi-core and hyper-thread (HT) technical checks: processor, vendorid, physicalid, siblings, coreid and cpucores. We can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. T

Layer-3 Ethernet switches are quite common, so I have studied the problems related to the CPU packet sending and receiving of layer-3 Ethernet switches. I would like to share them with you here, hoping they will be useful to you. Layer-3 Ethernet switches are developing rapidly. On the one hand, bandwidth and switching capacity of network devices are greatly increased, and the types of protocols supported by devices are also increasing with the increa

Why is the server so slow? CPU, RAM, and disk I/O resources are exhausted, and ram is used up Machine running is slow because it consumes too many system-specific resources. The main resources of the system include CPU, RAM, disk I/O, and network. Excessive use of any of these resources puts the system in trouble. However, if you can log on to the system, you can use a large number of tools to determine the

Cpu display information that you may not understand in CentOS command top When using the top Command, the following line is displayed: What are the meanings of each value in it? I was asked this question today and found that the answer is not very clear. Sure enough, the most frequently used top commands every day are still unknown... Shame... So I checked some information:Official explanation Cpu (s) indi

Tags: priority GitHub official item CTO how RTU iowait RelatedAdd by Zhj: Here's a good explanation of what WA means in the top command, and we know that when Io is blocked, the operating system changes the process to a blocking state, and the CPU is scheduled to run other processes.When the CPU is idle, it checks for blocked IO (disk or network), and if so, it is WA; if not, that is the real idle. In the t

For many enterprise users, performance is not the primary factor for server selection. The most important indicator is low power consumption and capital budget. AMD's latest haolong 4100 series processor is developed and designed for such users. The 4100 series is a low-level version of The Magny-Cours codenamed mainiku core haolong 6100 series processor. Haolong 6100 has two versions: 8-core and 12-core. In contrast, the "Lisbon" haolong processor is

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

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

1. clock speed The clock speed is also called the clock frequency. The unit is MHz, which indicates the computing speed of the CPU. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a misunderstanding of the server. So far, there is no definit

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

CPU of Linux system and performance monitoringPerformance optimization is the process of finding bottlenecks in system processing and removing them.

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
