Solve Win7 game card, network speed is slow

Since the release of Windows
7 system, many children's shoes have already used windows 7, but many children's shoes, especially gamers' children's shoes have such feelings, that is, Windows 7's network speed ratio xp To be slow, play games with high latency and play game cards. Therefore, many netizens will often ask: "I used it for a while. Windows
7 found that the network speed is slower than XP, playing game cards, windows 7 network speed is slow and the same computer
Using windows xp network speed is not slow, how is this going? ” For these Win7 system problems.

1. Set the QoS policy. What is QoS? QoS (Quality of Service) is a security mechanism of the network and is a technology used to solve problems such as network delay and congestion. Essential for critical applications and multimedia applications. When the network is overloaded or congested, QoS can ensure that important traffic is not delayed or discarded, while ensuring efficient operation of the network. Simply put, it is to improve the network priority of the game program to achieve the purpose of reducing the delay. The QoS strategy is mainly for web applications. Let's take the World of Warcraft game as an example. In the search window of the start menu, type “gpedit.msc” enter the group policy settings, find the "policy-based Qos" option, right-click to select a new strategy, here we named "rdow;wow", and then set the DSCP value For 63, then click Next.

Select this QoS policy to apply to “only for applications with this executable name", then enter the full path to the World of Warcraft WOW.EXE program in the field below and click Next.

Select the default to finish the last click, restart the computer, you can see the effect, according to the author's repeated tests, you can reduce the delay of about 80ms.
2, disable the MMCSS service If the above method does not solve the problem, we also try another way to delete the MMCSS service. The full name of the MMCSS service is the Multimedia Class Scheduler. The function of this service is to run in the service host Svchost.exe file, which automatically raises the priority of audio and video playback to prevent other software from over-consuming the CPU time that the playback software should receive. As a result, the CPU time allocated on the network will naturally be less, which will affect the network speed, so we can try to disable this service to reduce the game delay. First enter "ldedit" in the search window, enter the registry, find the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv item, double-click to open the DependOnService project on the right, delete the MMCSS, keep the other 2, and then click OK. Restart the computer. Then right click on “computer”, find "Multimedia Class Scheduler" in the service item, stop the service first, then set the startup type to "disable".

According to your own use, you can effectively reduce the delay of about 50ms across the FireWire.

In addition, this method can also be used to solve the problem of stable download speed in Windows 7 but watching online video and online live card. Knowledge Extension A thorough solution to the delay and hopping phenomenon: Many friends who use Windows 7 say that the system has a high network latency. Exhaustion of the method can not be solved, first of all, the method of changing the registry and deleting MMCSS and closing related services similar to XP has been effective. For friends who do not understand the registry, do not manually clean up the registration. Table garbage, you can choose software high color registry optimization master 2.1 to automatically clean up the registry garbage. Cleaning up the registry junk files can only solve some related problems, but to completely solve the delay and jump ping phenomenon, you must use the following small method.

First, we open the control panel, select the network and sharing center, click on the change adapter settings in the upper left, and then right click on the link you selected to select the property, the check in front of the internet protocol version 6 is canceled. Cancel the IPV6 protocol and click OK. Restart your computer (maybe you don't need to reboot) and you will find that the ping phenomenon has completely disappeared. The machine can quickly abandon XP and pick up Windows7.

WIN7 network speed is another solution There are some Win7 system beautification options will affect the Win7 network speed, causing Win7 to play the game card, enter the Windows7 control panel, find and open the color management. In the color management dialog that opens, switch to the Advanced tab and click Change System Defaults in the lower left corner. Subsequently, the system will pop up a dialog color management - system defaults. In this dialog box, also switch to the advanced option, and then cancel the system default check to use the Windows monitor calibration? After the modification is completed, save the settings to exit. It is recommended to turn off the Windows 7 theme auto update item. If you want to replace the Win7 theme, don't choose online update. Turning off some unnecessary online update options can reduce Win7 network speed delay to a certain extent, which is why some users report that their Win7 system sometimes plays game cards. Finally, I hope everyone can bring out their Win7 experience skills and share and learn with everyone!
