Improve the speed of computer system Win7 broadband Internet access

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, once When a TCP/IP packet data error occurs, all packet contents in the entire data buffer will be lost and retransmitted; obviously, re-transmission will greatly affect the efficiency of ADSL transmission 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 & rdquo;, restart the computer!

Feeling, is the Internet faster than before?
