How to improve the speed of Windows7 broadband Internet

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 meat.

By modifying the registry key to improve the speed of the Internet, this topic is really old enough, but old and new, computer novices are born every day, many friends use the computer and the network for the first time. Windows7 system, has not experienced 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!

Analysis of the principle of Internet acceleration:

Normally, TCP The default data transfer unit of /IP accepts a buffer size of 576 bytes. If the size of this buffer is set to be large, once an error occurs in a TCP/IP packet data, then all of the entire data buffer Packet content will be lost and retransmitted; 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, to manually modify is also very Convenient!

1. Open “Registry Editor> (Start-Run-Enter regedit);

2, which finds  HKEY_LOCAL_MACHINE\\System\\CurrenControlSet\\Services\\Tcpip \\Parameters”subkey;

3. In the right key area, find or create a DWORD key item named “GlobalmaxTcpWindowSize”; set its data value data to “256960” (decimal) ), of course, similar values ​​are also possible;

4, close & ldquo; Registry Editor & rdquo;, restart the computer!
