Windows 7 Tip Tweak TCP Settings

 

 

Right Click on Command Prompt > Select "Run as administrator

 

netsh int tcp show global  입력한 다음 ENTER 그럼 다음과같이 나옴니다.(저는 셋팅을 바꾼 상태 입니다)

 

 

 

TCP GLOBAL PARAMETERS NORMAL SETTINGS

 

RECEIVE-SIDE SCALING STATE : ENABLED

CHIMMY OFFLOAD STATE : DISABLED

RECEIVE WINDOW AUTO-TUNING LEVEL : HIGHLYRESTRICTED

ADD-ON CONGESTION CONTROL PROVIDER : NONE

ECN CAPABILITY : DISABLED

RFC 1323 TIMESTAMPS : DISABLED

 

 

A.TCP GLOBAL PARAMETERS TWEAKED

 

RECEIVE-SIDE SCALING STATE : ENABLED

CHIMMY OFFLOAD STATE : ENABLED

RECEIVE WINDOW AUTO-TUNING LEVEL : NORMAL

ADD-ON CONGESTION CONTROL PROVIDER : CTCP

ECN CAPABILITY : ENABLED

RFC 1323 TIMESTAMPS : DISABLE

 

 

B.TCP GLOBAL PARAMETERS tweaked

 

RECEIVE-SIDE SCALING STATE : ENABLED

CHIMMY OFFLOAD STATE : ENABLED

RECEIVE WINDOW AUTO-TUNING LEVEL : DISABLED

ADD-ON CONGESTION CONTROL PROVIDER : CTCP

ECN CAPABILITY : ENABLED

RFC 1323 TIMESTAMPS : DISABLED

 

 

C:\Windows\system32>netsh int tcp show global

                                         netsh int tcp set global rss=enabled

이런식으로 컴멘드 창에 입력 하시고 엔터키를 누르시면 됩니다. 그럼 OK 라고 나오면 적용이 된겁니다

TCP Auto-Tuning

netsh int tcp set global autotuninglevel=disabled

The default auto-tuning level is "normal"

 

disabled: uses a fixed value for the tcp receive window. Limits it to 64KB (limited at 65535).
higlyrestricted: allows the receive window to grow beyond its default value, very conservatively
restricted: somewhat restricted growth of the tcp receive window beyond its default value
normal: default value, allows the receive window to grow to accommodate most conditions
experimental: allows the receive window to grow to accommodate extreme scenarios (not recommended, it can degrade performance in common scenarios, only intended for research purposes. It enables RWIN values of over 16 MB)

 

RECEIVE-SIDE SCALING STATE  === netsh int tcp set global rss=enabled

 

netsh int tcp set global rss=enabled

netsh int tcp set global rss=disabled

 

CHIMMY OFFLOAD STATE-

 

netsh int tcp set global chimney=enabled

netsh int tcp set global chimney=disabled

 

ADD-ON CONGESTION CONTROL PROVIDER-

netsh int tcp set global congestionprovider=ctcp

netsh int tcp set global congestionprovider=none

 

 

ECN CAPABILITY- ( PLEASE NOTE IF YOU HAVE TROUBLE CONTACTING A SERVER I.E GAMES SERVER)

(DISABLE - ECN [ netsh int tcp set global ecncapability=default ])

netsh int tcp set global ecncapability=disabled

netsh int tcp set global ecncapability=enabled

netsh int tcp set global ecncapability=default
