HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\Class\NetTrans\000n (Where "000n" is your TCP/IP protocol. It contains "TCP/IP" assigned to the "DriverDesc" value. "n" can be any number from 0 to 9)
MaxMTU="1500" (string var) Note: If you're using DSL and your ISP has implemented PPPoE, you must set MaxMTU to 1492 or less.
HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\VxD\MSTCP
DefaultRcvWindow="256960" (string var, the maximum value of this setting is 2^30, or 1Gb in Windows 98/98SE/ME).
Note: For best results RWIN has to be a multiple of MSS (MaxMTU-40) lower than 65535 times a scale factor that's a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can simply make it multiple of MSS and turn scaling off (Tcp1323Opts=0)
DefaultTTL="64" (string var, range 1-255, use any number between 32 and 128)
PMTUDiscovery="1" (string var, boolean, 0-false or 1-true. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.
PMTUBlackHoleDetect="0" (string var, zero for optimal performance)
Tcp1323Opts="1" (string var, recommended setting is 1. The possible settings are 0 - No Windowscaling and Timestamp Options, 1 - Window scaling but no Timestamp options, 3 - Window scaling and Time stamp options.) The value is documented in RFC 1323
Note: According to Microsoft, Tcp1323Opts should be DWORD, rather than a string value, however seems that the documentation is wrong, and a string value is necessary to enable large RWIN values.
SackOpts="1" (string var, recommended setting is 1. Possible settings are 0 - No Sack options or 1 - Sack Option enabled) Selective Acknowledgements, as documented in RFC 2018
HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\VXD\MSTCP\Parameters
MaxDupAcks="2" (DWORD decimal var, taking integer values from 2 to N. Recommended setting is 2)
Recommended Registry Settings for Windows 95
According to Microsoft, the WinSock 2 update for Windows 95 supports TCP large windows and time stamps, which means you could use the Windows 98 recommendations if you update the original Windows Socket to version 2.
Windows Socket 2 update for Windows 95 - bug fixes from earlier implementations as well as some performance enhancements. Downloading the Winsock 2 update will allow you to add the Windows 98 entries as well.
Here are the recommended settings supported by the original and the updated versions of Winsock.
HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\Class\NetTrans\000n (Where "000n" is your TCP/IP protocol. It contains "TCP/IP" assigned to the "DriverDesc" Value)
MaxMTU="1500" (string var) Note: If you're using DSL and your ISP has implemented PPPoE, you should set MaxMTU to 1492 or less.
HKEY_LOCAL_MACHINE\
System\CurrentControlSet\Services\VxD\MSTCP
DefaultRcvWindow="64240" (DWORD decimal var, or string var, has to be a multiple of MSS for best results, i.e. (MaxMTU-40) x number... The range of this setting Windows 95 is range 0-65535. Best settings to try with MSS=1460 are 64240, 46720, 23360 and 11680, in that order)
DefaultTTL="64" (string var, range 1-255, use any number between 32 and 128)
PMTUDiscovery="1" (string var, boolean, 0-false or 1-true. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.
PMTUBlackHoleDetect="0" (DWORD decimal var, zero for optimal performance)
Windows NT 4 Registry Tweaks
Windows NT is slightly different in handling TCP/IP than Windows 9x. Keep in mind that even if you apply the Windows NT tweaks, you'll see smaller performance increase than with Windows 9x, simply because NT is better optimized for networking. I strongly recommend backing up your Registry before applying these settings.
HKEY_LOCAL_MACHINE\
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
"TcpWindowSize"="64240" (DWORD decimal var, range 0-65535. It has to be a multiple of MSS for best results, i.e. (MaxMTU-40) x number... Recommended settings to try are 64240, 32120 and 8760 , in that order)
DefaultTTL="64" (DWORD decimal var, range 1-255, use any number between 32 and 128 )
EnablePMTUDiscovery="1" (DWORD decimal var, boolean, 0-false or 1-true. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.
EnablePMTUBHDetect="0" (DWORD decimal var, boolean, 0-false or 1-true. Set to 1 if you decide to set "EnablePMTUDiscovery" to 1)
HKEY_LOCAL_MACHINE
\SYSTEM\CurrentControlSet\Services\<Adapter Name>\Parameters\Tcpip
MTU="1500" (DWORD decimal var, Range 68 - <Value of the Network>. Values larger than the default for the underlying network will result in the transport using the network default MTU) Note: If you're using DSL and your ISP has implemented PPPoE, you should set MaxMTU to 1492 or less.
ㅡㅡ;; 몽땅 영어지만 이 정도면 충분할껍니다.
이건 dsl이나 케이블 환경에 맞추는 프로그램입니다.
