CPU clock speed, that is, the clock frequency (cpuClock speed ). In general, the CPU is as high as, And the is the "CPU clock speed ". Many people think that the CPU clock speed is its running speed. The clock speed of the CPU indicates the speed at which the digital pulse s

Article Title: CPU load in Linux. Linux is a technology channel of the IT lab in China. Some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems view the Nagios alarm information yesterday and find that one of the servers is overloaded with CPU and the machine is CentOS. The information is as follows: 2011-2-15 (Tuesday) 17: 50 W

In the Linux system, the software and hardware information of proc file system display system is supplied. If you want to understand the system of CPU suppliers and coherent device information, it can be obtained through the process/proc/cpuinfo file. This article makes a brief summary of the file.Unlike the/proc/cpuinfo file generated by the instruction set (ISA) CPU, the/proc/cpuinfo file based on the X86

balanced definition of the various OS subsystems. These subsystems include:CPUMemoryIoNetworkThese subsystems are mutually dependent, and any high load will cause problems in other subsystems. For example:Memory queue congestion caused by a large number of page call requestsThe large throughput of the NIC may cause more CPU overhead.A large amount of CPU overhead will try more memory usage requestsA large

Metrics to measure CPU performance:1, the user uses the CPU situation;CPU runs regular user processesCPU Running niced ProcessCPU running real-time process2, the system uses CPU condition;For I/O Management: interrupts and drivesFor memory management: page swappingUser Process Management: Process start and context swit

In general, MySQL optimization can be divided into two levels: one is Optimization at the MySQL level, such as SQL rewriting, index addition, and configuration of various MySQL parameters; the other layer is the operating system and hardware. Operating system-level optimization in general, MySQL optimization can be divided into two levels, one is on the MySQL-level optimization, such as SQL rewriting, index addition, the configuration of various MySQL parameters. The other layer is the optimizat

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

This article is reproduced from Inter official website: https://software.intel.com/zh-cn/articles/book-Processor-Architecture_CPU_work_processThe working process of the CPUThe basic work of the CPU is to execute the stored instruction sequence, which is the program. The process of executing a program is actually the process of constantly taking out instructions, analyzing instructions, and executing instructions.The

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

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

Linux command ---- analyze CPU bottlenecks to measure CPU performance indicators: 1. CPU usage; CPU running regular user processes CPU running nicedprocessCPU running real-time processes 2. CPU usage; for IO management: interrupt

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
