How to modify GlobalMaxTcpWindowSize for better upload speeds

Configurare noua (How To)

Situatie

This value has a long name, but you won’t regret modifying it if you have a big Internet connection (10 Mbps and up) and often upload stuff. This value represents how much data can be sent from your computer without receiving an acknowledgement (ACK) packet.

Every time you send small chunks of data on the Internet, your computer has to wait for this packet, which tells your end of the network, “Everything’s OK! Send more!” Sometimes, due to latency and poor peering, this might not be ideal. So, you can edit this value to allow more data to be sent without waiting for that packet to come.

Solutie

Pasi de urmat

Create a DWORD called “GlobalMaxTcpWindowSize” in the following registry path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Set the value to 65535 and you’re done! This will make the computer able to send 64 kilobytes without waiting for acknowledgement. If you feel a drop in speed after modifying this, either remove the value or try raising it slightly to 128 kilobytes (by setting the value to 131072).
