How to speed up the Internet

If you are using a LAN network that is especially bad, or if you are using a broadband connection, setting the appropriate Tcpwindow value in the registry can speed up the Internet. (Please note: If the speed of the normal effect is not obvious)

Open Registry Editor (easiest way: Start--run the input regedit on it), locate the "Hkey_local_machinesystemcurrencontrolsetservicestcpipparameters" subkey in it , in the right key value area, locate or create a new DWORD key value named "Globalmaxtcp windowsize", set its data value data to "256960" (decimal), close Registry Editor, and restart the computer. Do you feel the speed is much faster than before?

The rationale for this change is that the TCP/IP default data transmission unit accepts a buffer size of 576 bytes in general, and if the size of the buffer is set to large, all packets in the entire data buffer are grouped as soon as a TCP/IP packet data error occurs. are lost and retransmitted; it is obvious that the retransmission will greatly affect the efficiency of ADSL data transmission. To this end, set the appropriate buffer size to ensure that ADSL transmission data is always high efficiency, will have a direct impact on ADSL transmission speed!

Warm tip: The computer knowledge of a few friends, we suggest you do not casually modify the parameters of the registry, or please understand the computer knowledge of people to help.
