Knowledge about Linux CPU and Linux CPU
What is the difference between hyper-threading and multithreading?
Hyper-threading is understood from the hardware layer, that is, a CPU component (which can be understood as a core) executes multiple commands at the same time, which means that multiple threads are executed at the same time.Multithreading is a concept at th
Today, a problem arises: what is a 32-bit CPU, a 32-bit OS, and a 32-bit program? Why can 32-bit CPU only support 4 GB memory?
This problem occurs. Today, I ran SSIS and found that the memory was not enough. I checked the memory and found that 4 GB memory only showed more than 3 GB memory. I want to add memory. But I have heard that 32-bit computers can only support 4 GB memory at most. Why? I don't know.

Computer used for a long time, the computer will be a lot of ash, especially the CPU fan, resulting in poor heat dissipation, slow running and so on a series of problems. Today's small knitting to teach you how to remove the CPU fan.

First, the conclusion is listed in the front:
Golang performance can be very good, but some native package performance is likely to be retarded, such as RegExp and Encoding/json. If used in high performance requirements, we should optimize according to the actual situation.

Possible factors:1. Ambient temperatureThe cpu temperature has a lot to do with the ambient temperature. It will be a little higher in summer. Generally, the temperature is less than 50 ° when the CPU is idle, less than 65 ° when the CPU is busy, and less than 75 ° when the CPU is working at full speed. In
Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs.
For details, FSB is P
Have seen a few times before the concept, but still always remember, simply write it down, easy to see in the future ~The so-called clock time is also called the wall clock time, it is the total number of clocks that the process is running, and its value is related to how many processes are running concurrently in the system, although it is generally measured when there are no other activities in the system when discussing clock time.User CPU Time: Is

CPU is the central processor. This is a super-large-scale integrated circuit. It is the computing core and control core of a computer and the main part of the computer. How can we solve this problem if the cpu usage of win7 is too high?Method 1: reduce the computer startup service items. Click "start" in the lower left corner of the desktop and enter "msconfig" in the "run" dia

To explain the above command, the PS command displays the status of process information for the current system, its "-e" parameter is used to display all processes, and "-l" is used to display the thread (light-weight process). "-o" indicates custom format output. Ruser
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.
