Disadvantages of optimizing dual-core processor compatibility

With the development of science and technology, dual-core processor is very common in our life, dual-core processor (Dual core Processor) refers to the integration of two computing cores on one processor to improve computing power.

You can open Task Manager, click Performance, you can see the CPU's working status.

Although in most cases, dual-core work is our best choice. However, in some cases, dual-core processors also have their drawbacks. For example, some older programs that run with a dual-core processor can cause exceptions such as card machines.

In Windows7, you can configure multiple core processors to use only one or several cores when the application is running.

Below I will tell you the specific steps:

Task Manager

Ctrl+alt+delete Open Task Manager, select application Options, left-click the application you want to set--right--go to the process and you'll go to the process options interface.

Then right-click to select Set dependencies.

This way you can see control of the CPU core running and you can set your own way according to your needs.

Take a look at the impact

You can turn on Microsoft's own Disk Defragmenter and then go to the Performance options for task management by clicking on the Resource Monitor option below.

You can clearly see the CPU at each core of the operation, according to their own needs to configure and see the different performance between.

Create shortcuts

If you find that the running application works faster at a specific processor core, and you often use this program, you can set up keyboard shortcuts to manipulate it, so let's start with Disk Defragmenter for example, hoping to help a little bit.

Win 7 system desktop

To start Disk Defragmenter, just want it to run only in CPU0, you can create a shortcut with the following command:

C:WINDOWSSYSTEM32CMD.EXE/C start/affinity 1 Dfrgui.exe

If you want Disk Defragmenter to run only in CPU1, you can create a shortcut with the following command:

C:WINDOWSSYSTEM32CMD.EXE/C start/affinity 2 Dfrgui.exe

If you want the Disk Defragmenter to run at two cores, you can create a shortcut with the following command:

C:WINDOWSSYSTEM32CMD.EXE/C start/affinity 3 Dfrgui.exe

Start Disk Manager for the central processing Unit O and 1, if you convert the affinity after 3 to binary number 011, then to line CPU0 and CPU1,

If you have a quad core processor, the affinity will run CPU2 after it turns 4, and if it becomes 9, run CPU0 and CPU3.
