What does cpu utilization mean?

Cpu utilization (usage rate) is the CPU resources occupied by programs running on the machine, indicating how the machine is running programs at a certain point in time. High CPU utilization means that the machine is running many programs in a certain period of time, and vice versa. The level of CPU usage is directly related to the strength of your CPU. The CPU's response to threads is not continuous and usually automatically interrupts the thread after a period of time. As the number of unresponsive threads increases, the CPU usage will continue to increase, thereby increasing the CPU usage.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Cpu utilization, that is, cpu usage, is the CPU resources occupied by programs running on the machine, indicating how the machine is running programs at a certain point in time. The higher the CPU usage, it means that the machine is running a lot of programs in a certain period of time, and vice versa.

The level of CPU usage is directly related to the strength of your CPU. The operations of all software layers in the computer system will eventually be mapped to CPU operations through the instruction set. The CPU's response to threads is not continuous and usually automatically interrupts the thread after a period of time. As the number of unresponsive threads increases, the CPU usage will continue to increase, thereby increasing the CPU usage.

Under normal circumstances, it is normal for the CPU usage frequency to remain below 50%. When no program is running, the CPU usage frequency may reach below 15%, which is also normal. of.

But since the CPU mainly determines its execution behavior based on instructions fetched from memory, fragmentation may occur during the decoding process, so when the computer CPU utilization varies between 0% and 75% , this is a very normal phenomenon, but if it occurs frequently, the utilization rate reaches more than 90%. Then it is necessary to conduct a complete inspection of the computer.

Possible reasons for high CPU usage

1. Automatic updates of the operating system or anti-virus software. When the operating system or anti-virus software detects an updated module on the Internet, it will automatically update. This will take up a lot of CPU.

2. Anti-virus software automatically removes viruses. If you set the anti-virus software to automatic anti-virus or regular anti-virus, it will automatically run the anti-virus program when the anti-virus time comes. It will also take up a lot of CPU.

3. The driver has not been certified, causing CPU resources to occupy 100%. A large number of beta drivers are flooding the Internet, causing hard-to-find fault causes.

4. The computer is infected with viruses or Trojans. A large number of worms quickly replicate within the system, causing the CPU resource usage to remain high.
