When buying a computer, sometimes the staff will ask you, what is the main purpose of the computer? You don't need to run large-scale software, so as not to cause the CPU of the computer to be too high. Some people don't know what the meaning of the CPU of the computer is, and what will happen if the CPU utilization rate of the computer is high. Today's editor will tell you about the CPU of the computer
Reasons for high CPU utilization
1. Software
This aspect mainly relates to the system problems, such as the system is too bloated, open too many programs, virus Trojans in the computer and so on, which will lead to high CPU utilization and slow computer speed. The main solution is to optimize the system, optimize startup items, try to avoid opening too many programs and so on.
2. Hardware
In fact, the hardware determines a relatively large relationship. For example, if a computer or a master computer uses the original single core Celeron processor, such a computer will easily lead to high CPU utilization when it opens several more web pages. No matter how you optimize the system, this problem can never be solved well, which is mainly caused by the low hardware itself.
But now the computers have reached the dual core or above. Even the entry-level processor can run at a very smooth speed to meet the needs of surfing the Internet and working. Therefore, if the CPU utilization rate of the old computer is often too high, it is recommended that you upgrade the processor or change the computer to fundamentally solve the problem. For today's entry-level dual core processor, although it meets the basic requirements of online and office fluency, there will also be high CPU utilization when running large-scale applications. Therefore, in DIY installation, we must understand the purpose and demand of computers and select the appropriate computer configuration.
What is the impact of high CPU usage
CPU CPU utilization is actually the CPU resource occupied by the program you run, which indicates the running of the program by your machine at a certain point in time. The higher the usage rate, the more programs your machine runs at this time, and vice versa. The usage rate is directly related to the strength of your CPU.
Modern time-sharing multitask operating system uses CPU in time slices: for example, process a takes up 10ms, process B takes up 30ms, then idle 60ms, then process a takes up 10ms, process B takes up 30ms, and idle 60ms. If this is true for a period of time, the occupancy rate for that period is 40%. The response of the CPU to the thread is not continuous, and it usually interrupts the thread automatically after a period of time. The increase of unresponsive threads will increase the CPU usage.
When the machine slows down, of course, we think of task manager. Let's see which program accounts for a higher proportion. If it's a large program, it's forgivable. After closing the program, as long as the CPU is normal, it's OK. If not, then you have to see what the program is, when you can't find out what the process is, go online search. Sometimes it's useless to just end. Under XP, we can combine the startup items in msconfig to turn off some unused items. You can go to the next WinPatrol under 2000.
The solution of high CPU utilization
CPU if the computer virus or horse situation, Trojan horse malware is likely to occupy a large number of CPU resources, especially some stubborn virus Trojan horse, has been malicious cycle activities, infecting various system files, a large number of CPU resources, this situation is very easy to appear CPU utilization rate is too high, we suggest that we use anti-virus software to carry out a comprehensive killing.
After virus infection is eliminated, we need to start with system optimization. First, we suggest that you optimize the startup items, and try to make the software that does not need to be used not start automatically, such as some player software, bank security plug-ins, etc., which can be started again when it is necessary, without starting. If we find that the CPU utilization is high, we can also enter the task manager and close some unnecessary programs and processes.
Service key optimization through the registry can also optimize the use of CPU resources to a certain extent. For example, when the system checks to open video related services, it will allocate more CPU for its use. We just need to disable this mechanism. First, we enter the computer registry, and then only keep audioendpointbuilder and rpcss in the numerical data, delete all others, and then exit. By disabling this useless function, we can also slightly improve the CPU resources. In addition, we can also optimize other items in the registry. We will not introduce them one by one here.
