By modifying the registry key to make the Win7 system broadband network accelerate

, although most of the factors that determine the Internet access are broadband traffic. Relatively speaking, the role of speeding up the Internet on the machine is the mosquito meat, but how to say it is also meat. . By modifying the registry key, the Internet speed is improved.
This topic is really old enough, but old and new, computer novices are born every day, many friends first contact the computer and the network is using Windows7 system, did not experience DOS, Win95, Win98 or even XP era.
Before the beginning of this article, let's talk about the principle analysis of acceleration. If it is wrong, please correct me!
The analysis of the principle of Internet acceleration:
Under normal circumstances, the default data transmission unit of TCP/IP accepts buffer. The size of the area is 576 bytes. If the size of this buffer is set to be large, once an error occurs in a certain TCP/IP packet data, all packet contents in the entire data buffer will be lost and performed. Retransmission; apparently re-transmitting, will greatly affect the efficiency of ADSL transmission of data. To this end, set the appropriate buffer size, to ensure that the efficiency of ADSL transmission data is always high, will have a direct impact on the ADSL transmission speed!
Do it yourself, full of food and clothing, know the principle, it is very convenient to manually modify!
1, open " Registry Editor " (Start-Run-Enter regedit);
2, which find "HKEY_LOCAL_MACHINESystemCurrenControlSetServicesTcpipParameters" sub-key;
3, in the right-key area, find Or create a new DWORD key-value item named "GlobalmaxTcpWindowSize"; set its data value data to "256960" (decimal), of course, similar values ​​are also possible;
4, close "registry editing ", restart your computer!
