Windows7 network acceleration setting method

Many users have such a question, broadband network speed computer
can set acceleration? Of course, although the majority of factors that determine the Internet access is broadband traffic Relatively speaking, the effect of speeding up the Internet on the machine is the mosquito meat, but how to say it is 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 with computers and networks are using Windows
7 system, no experience Over the days of DOS, Win95, Win98 and even XP.

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!

Try to open the web page or QQ, the game Class, do you think that win7 Internet speed is much faster than before? Of course you can also measure speed
