CPU utilization good understanding, that is, CPU utilization, more than 75% is higher (also has the argument is 80% or higher). In addition to this indicator, but also in combination with the load average and context Switch rate, it is possible that the high CPU is due to the latter two high indicators.
Load Average, this is hard to measure. Online Search a la

When you use bash to start a program, you can use it after adding to implement the program to run in the background;
Example: emacs
But if you forget to enter ; but you do not want to stop the program and restart it;
You can do this:
Press Ctrl + Z to pause front-end work, such as the Emacs mentioned above;
Run the jobs command to check the total number of programs started by bash. You can se

Start a number of threads of the program in the shutdown when there is a problem, if the program exits without closing the thread, then the thread will always exist, but most of the start of the thread are local variables, can not be closed, if the call Thread.CurrentThread.Abort () Method closes the main thread, a ThreadAbortException exception appears, so this is not possible.
Later found this approach: Thread.IsBackground set the thread as a background thread.

What is the difference between the server CPU and the normal CPU? Below we find a professional literature, quickly to increase knowledge. Overall, there are six main differences between the server CPU and the common computer CPU, so let's look at it together.
One, the instruction set is different

If you put the web in front of you, it's about the web, primarily the Internet, and you can include mobile networks and other media networks, such as IPTV, because the idea is consistent.
Now it is very rare to find a WEB foreground developer that meets the skill requirements of graduating students. a
With the improvement of computer performance, the CPU power consumption is also increasing, although now because of improved technology to achieve a certain degree of mitigation in power, but because of the increasing performance of the graphics card in recent years, also began to take the CPU power performance proportional to the old road, power consumption is still a worthy of attention, power consumption
the central Processing Unit (PROCESSINGUNIT,CPU) is the computing core and control core of a computer. CPU, internal memory and input/output devices are the three core components of computer. Its function is mainly to interpret computer instructions and to deal with data in computer software. The CPU consists of an operator, a controller and a register, and a b
From the software point of view of the CPU, it seems that the CPU is a series of instruction symbols. Therefore, we design a CPU, first of all to consider which instructions should be designed. The instruction system of the computer needs to be planned according to the requirement of the task, there will be arithmetic operation instruction, logic operation instru
High CPU usage is a frequent problem for netizens, CPU usage is actually the CPU resources that you run the program, which means that your machine runs a lot of programs at this time. Long-term use will make the CPU for a long time in the hot state will affect the impact of the CPU

Terminals with control terminals belong to the frontend, and those with no control terminals or hidden background processes are called background processes.
This may be very abstract. The actual example is more specific, such as anti-virus software. If you open his console, you can perform various operations such as hard disk scanning. At this time, he is a front-end process. When you hide his control terminal, it is a background process.
