Win7 system broadband network acceleration tips

Although the majority of factors that determine the Internet access is broadband traffic, relatively speaking, the role of speeding up the Internet on the machine is the role of 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 old, computer
novices are born every day, many friends first contact computer
and network
is using Windows7 Systematic, 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! The analysis of the principle of Internet acceleration:

In general, the default data transmission unit of TCP/IP accepts the size of the buffer. For 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 retransmitted; Obviously, re-transmission 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, get enough food, know the principle, it is very convenient to manually modify it!

1, open “ Registry Editor> (Start-Run-Enter regedit);

2, where "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!
