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

Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate. First, traces of the Thunder Why can reduce CPU occupancy rate 1. Deep understan

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

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.

Walk the computer market and you'll be pleasantly surprised to find that computers configured with more than 1Ghz of CPUs have become the mainstream of the market. When the CPU is more than 1GHz, the maintenance of the hardware CPU becomes the first important event, if still not enough attention, will cause computer failure or even crash, burn. CPU is like a huma

When we use the Windows XP operating system, we are slow to use it, and we see "Task Manager" to find that CPU occupancy is up to 100%. What the hell is going on? There is a virus, hardware problems, or system settings have problems, in this article I will be from the hardware, software and virus three aspects to explain the system resource occupancy rate of why it will reach 100%. 　　nine possibilities for high CP
