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

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

When using the top command, we will see this line: What do the values in it mean? 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: The official explanation of Cpu (s) indicates cpu information. The meaning of each value is: us: usercputime (or) % CPUtimespenti

The kernel often requests and frees a single page box. To improve system performance, each memory management area defines a per-CPU page box cache. All "per CPU" caches contain pre-allocated page boxes that are used to satisfy a single memory request made by the local CPU.Provides two caches per memory area and per CPU: a hot cache, which holds content contained

Do system operation, monitoring CPU is a frequent thing, then need to pay attention to what indicators?????Run Queue StatisticsIf you want to see how busy the CPU is, we can make a simple judgment by looking at the status of the process in the system, for example, by looking at the number of runnable processes and the number of blocked processes to CPU utilizatio
