ADSL optimization is imperative. We have introduced the simple optimization method of ADSL registry (general method). Now specifically for users using Windows XP, our optimization strategy is introduced as follows:
(Note: This method is only applicable to ADSL users of PPPoE mode)
Before making these modifications, please make a backup of the registry first so that it will recover when it is not suitable for your situation or when it is modified and errors are modified. At the same time, the optimization methods introduced here are not guaranteed to play a role in your area due to the differences in the networks in different places.
Windows XP Optimized Registration
Windows XP comes with PPPoE dialing, which further comprehensively optimizes network connections, so we can greatly reduce the areas we can optimize. According to the official Microsoft information we currently have, we can still make appropriate optimization and adjustments to the following places.
Open the Registry Editor (Start Menu -> Run -> Input -> OK) Add the following values to the following items:
1.HKEY_LOCAL_MACHINE\System\Ccs\Services\Ndiswan\Parameters\Protocols\0
Add the following 2 key values under this project to effectively modify the MTU parameters of Windows XP
****Name: ProtocolType
****Type: REG_DWORD Double Byte
****Key value: 0x0800
****Name: PPPProtocolType
****Type: REG_DWORD Double Byte
****Key value: 0x0021
You can now increase the key key value of the control MTU
****Name: ProtocolMTU
****Type: REG_DWORD Double Byte
****Key value: 1492
ADSL's PPPoE users generally set MaxMTU to 1492 or less, and enter the correct value based on their own detection results.
2. According to the Microsoft Database description, we can directly use the following optimization and modifications of Windows 2000.
Add the following values to the following items:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
SackOpts=0000001 (double byte DWORD value)
TcpWindowSize= 0003e640 (double byte DWORD value)
Tcp1323Opts=0000001(double byte DWORD value)
DefaultTTL =00000040 (double byte DWORD value)
EnablePMTUBHDetect =00000000(double byte DWORD value)
EnablePMTUDiscovery =0000001 (double byte DWORD value)
GlobalMaxTcpWindowSize =0003ebc0 (double byte DWORD value)
If you use PPPoE connection, it is recommended to use 0003e640
