How to speed up Windows7 broadband Internet speed

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 first contact the computer and the network is using Windows7 system Have 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!
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!
Registered expression: manual labor
do it yourself, full of food and clothing, know the principle It is very convenient to manually modify it!
1, open “ Registry Editor> (Start-Run-Enter regedit);
2, which finds "HKEY_LOCAL_MACHINESystemCurrenControlSetServicesTcpipParameters"; sub-key;
3 In the right key area, find or create a DWORD key value named "GlobalmaxTcp WindowSize"; set its data value data to "256960" (decimal), of course, similar values ​​are also possible; Br> 4, close & ldquo; Registry Editor & rdquo;, restart the computer!
Feeling, is the Internet faster than before?
