Usually use the computer often encounter slow speed, in general, because the CPU occupancy rate is too high, then how to operate it? Small series here to give the answer, take a look at it, hope to help everyone!
When the machine slows down, the first thing we think of is, of course, the task manager, to see exactly which program accounted for the ratio, if it is a large program that can be forgiven, in th
the WIN10 built in DX12 is good for the gaming experience, but the high version of DX also puts a higher demand on CPUs and graphics cards. Microsoft's DirectX has gone through 12 versions, whether it's hardware or games, and has changed dramatically, and advanced technology has brought us a better gaming experience.
Is DX12 CPU demanding? The effect of the old driver's

", where multiple threads modify the "competitive behavior" caused by shared resources, forcing the modules we use to support "thread safety". Therefore, it has somewhat increased the instability of web services. For example, the PHP extension used by mod_php also needs to support "thread safety", otherwise it cannot be used in this mode.
Pros: Take up less memory and perform better with high concurrency.
Disadvantage: Thread safety must
time, the larger the number, it usually indicates that the system is running slower. US: The percentage of CPU time consumed by user mode. A higher value indicates that the user process consumes more CPU time, for example, if the value is longer than 50%, you need to optimize the program algorithm or code. SY: The percentage of
method is simple and effective: In general, the hands do not feel the temperature of about 25 ℃, there is a feeling of temperature in the 35 ℃ degree or so, warm, that is very warm feeling should be around 45 ℃; Heat but can also continuous contact should be in the 55 ℃ or so, feel hot but can endure 35 seconds of temperature due to in 70 ℃ or so, feel very hot, contact to regret touching it, die do not want to contact the time should be 80 ℃ or so.

3. how to measure CPU usage in Linux
1) CPU utilization: the most intuitive and important thing is the CPU usage. If it exceeds 80% for a long time, it indicates that the CPU has encountered a bottleneck;
2) User time: the CPU used by the User
, Unfortunately you've been scalded, which is estimated to be above 250 ℃. But we know, even if we feel the bottom of the temperature should be around 55 ℃, then the CPU temperature should be not less than 65 ℃ it. And CPU temperature once more than 75 ℃ and long time work, light is dead, heavy is burnt out. In the process of using a notebook, if it is obvious th
, open process or program too much, poisoning, these conditions can lead to CPU 100%, so that the CPU full operation, the temperature is too high.
3.CPU overclocking. CPU frequency is high
CPU is the computing core and control core of a computer. We carry out computer operations need to deal with the CPU, once the CPU usage rate is too high, it will affect the processing speed, so that the computer slow down, if the CPU reached 100% may also cause the operatio
