In Linux, you can view CPU and memory usage during system maintenance. You may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage
release of the driver to install, and sometimes appropriate upgrades to drive, but remember the latest is not the best.
CPU cooling software, because the software in the runtime will use the CPU idle time to cool, but windows can not distinguish between ordinary CPU consumption and cooling software cooling instructions between the difference, so the
In linux, you can use top or vmstat to view the system's CPU usage. In most cases, the CPU usage is accurate, but in real-time linux systems with high time precision, the CPU usage measured by top may be inaccurate. The following
In the absence of nagios monitoring software, as long as the server can be on the Internet, you can send mail to remind the Administrator system load and CPU usage.
First, install the following Linux mail client msmtp software (similar to a foxmail tool)

Hyper-V 3 limits the CPU utilization of virtual machines. Windows Server 2012 is coming soon. The latest Hyper-V 3 brings us more surprises, in the next three blog posts, we will learn about the virtual machine CPU competition mechanism. Part 1: CPU resources allocated to virtual machines; Part 2: limits the CPU
CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. Higher usage means that your machine runs a lot of programs at this time, whereas lessThe top command is a common system performance analysis tool under Linux that allows you to vie

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
