occupancy rate was {bfb} sure that the long-term abnormal

In fact,, this is a normal phenomenon, "System Idle Process" of the Chinese name is "system idle process\Therefore, it values the greater the more the available CPU resources, and vice versa.
here, by the way, there are a lot of

2. refusal to real-time monitoring program
There are many software designed real-time monitoring modules, such as a variety of real-time anti-virus software updates / upgrades virus database, e-mail auto-detection procedures, and systematic plan tasks. These procedures and plans for the tasks proposed to abolish the common monitoring capabilities, or shorten the cycle of real-time monitoring.

many readers prefer to use the Internet when

addition to the above list and analysis of the phenomenon, there are a lot of CPU utilization caused by the high otherwise. For example system is installed to the imperfect or non-compatible hardware
