Problem:Run the vmstat, top, and PS aux commands to view the CPU usage of the process. The value varies greatly.
Example:Use vmstat to view the system's CPU idle rate. The ID is the CPU idle rate. It can be seen that the idle rate is always above 73%.Use PS aux to count the CPU
Solution:1. The driver has not been certified, resulting in 100% of CPU resources. A large number of beta drivers are flooding the Internet, leading to hard-to-find fault causes.2. Faults caused by anti-DDoS and anti-virus software. Some anti-virus software has added random monitoring of web pages, plug-ins, and emails, which undoubtedly increases the burden on the system. You can choose to enable the service as needed.3. Viruses and Trojans. A large
