Win7 broadband speed method and Internet accelerator principle

The most painful use of the computer is the Internet speed, if the Internet speed is fast, then it must be very cool. And if the Internet speed is very slow, the web page is very card. So the feeling is very uncomfortable, then how to speed up the Internet speed using win7? What is the principle of Internet acceleration?
1
The principle of Internet acceleration:
TCP/IP default data transmission The size of the unit accept buffer is 576 bytes. If the size of this buffer is set to be large, once a TCP/IP packet data error occurs, all the packet contents in the entire data buffer will be Lost and retransmitted; 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!

How to set the buffer size
Enter the registry editor Click Start and type regedit in the search box.

Then locate: HKEY_LOCAL_MACHINESystemCurrenControlSetServicesTcpipParameters
In the right key area, find or create a DWORD key item named “GlobalmaxTcp WindowSize”; set its data value data to “256960”; (decimal),
