Before the beginning of this article, let's talk about the principle analysis of acceleration. If it is not right, please correct me!
Internet acceleration principle analysis:
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 a TCP When an error occurs in the /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!
Specific modification steps:
1. Software up to people: lazy people are smart people
The place where you can drive does not walk, efficiency first, who remembers so many registry keys every day, come and come Open Rubik's Cube or Windows 7 Optimizer.

2, which found the "HKEY_LOCAL_MACHINE\\System\\CurrenControlSet\\Services\\Tcpip\\Parameters" sub-key;
3, in 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;
4, Close the "Registry Editor" and restart your computer!
It feels like, is the Internet faster than before?
