by modifying the registry key to improve the Internet speed, this topic is really old enough, but old and old, computer novice but every day, many friends for the first time Contact with the computer and the network is using Windows7 or Vista 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 not right, please correct me! Analysis of the principle of Internet acceleration: Under normal circumstances, 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/IP packet data error occurs. At this time, all the contents of the packet in the entire data buffer will be lost and retransmitted; obviously, the 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: First, the software up to people: lazy people are smart people can drive the place does not walk, efficiency first, who remembers so many registry keys every day, come and come, open the Rubik's Cube or Vista optimization master. Inside the optimization guide of Rubik's Cube or Vista Optimization Master, the network optimization part, select xDsl (ADSL, VDSL, etc.) to automatically set it for you.
Or, go to the advanced settings page: 1. Click on the cube above "System Optimization", "Network Acceleration" 2. Select xDsl (ADSL, VDSL, etc.), click the "Automatic Optimization" button in the lower left corner, and then click " Save the settings button;

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 the "Registry Editor", restart the computer can!
