Speed ​​up Windows7 broadband Internet speed

The most important factor in determining the Internet is 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, the default data transmission unit of TCP/IP accepts a buffer size of 576 bytes. If the size of this buffer is set to be large. If there is an error in a certain TCP/IP packet data, then 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!

Registered expression: manual labor

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. Find "HKEY_LOCAL_MACHINE\\System\\CurrenControlSet\\Services\\Tcpip\\Parameters” Subkey;

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

4, close “ Registry Editor”, restart the computer!

It feels like, is the Internet faster than before?
