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
A while ago, I suddenly became interested in the working principle of computer hardware. Therefore, I read some documents, and I have summarized and understood (and guessed) them. I will give you the following article.
Appendix: This article only analyzes the CPU interruption technology theoretically, but does not analyze the implementation of the interrupt technology.

1. What is CPU int
Because of the management problems in our alization are caused by the annoyingly popular desirable host Migration Feature! I previusly talked about PCI device addressing problems, but this time the topic to consider is that of CPU models. every hypervisor has its own policies for what a guest will see for its CPUs by default, xen just passes through the host CPU, with qemu/KVM the guest sees a generic mode
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

1, anti-virus software caused the failure
Because of the new version of KV, Jinshan, rising are added to the Web page, plug-ins, mail random monitoring, undoubtedly increased the system burden. Treatment: Basically there is no reasonable treatment, try to use the least monitoring services, or, upgrade your hardware equipment.
2, the driver has not been certified, resulting in 100% CPU resource consumption
A large number of beta drivers are flooding
In the DIY computer field, many players in the installation, attention is often focused on the computer performance of the CPU, graphics, motherboards, memory, hard disk and other core hardware, on the chassis power, radiator and other hardware often do not care too much. Because of this, some friends assembled computers are often equipped with some of the inferior radiator, cottage chassis power supply and so on, in the future when used, it is very e
