why i can not get same "netsh int tcp show global" settings with win 8 as 7?

[jgeny]

i have a tyan s7025 with two xeon 5520 . i installed win 7 x64 ultimate and win 8 pro x64 .

with win 7 if i use the command : netsh int tcp show global then the result is :

Microsoft Windows [Version 6.1.7601]

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

Querying active state...

TCP Global Parameters

----------------------------------------------

Receive-Side Scaling State : enabled

Chimney Offload State : enabled

NetDMA State : enabled

Direct Cache Acess (DCA) : enabled

Receive Window Auto-Tuning Level : normal

Add-On Congestion Control Provider : ctcp

ECN Capability : disabled

RFC 1323 Timestamps : disabled

while with with 8 on the same mainboard with drivers being latest too , i get :

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

TCP Global Parameters

----------------------------------------------

Receive Window Auto-Tuning Level : normal

Add-On Congestion Control Provider : none

despite i added in registry some new keys :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

EnableDCA=1 and EnableTCPA=1

they have no effect even many reboot ... while my settings in win 7 were done without anything in the registry except using tcpoptimizer from speed guide

what should i do ?

i also be glad if someone gives a link to a wiki about the registry keys for tcip and the different windows releases, even something [improbable] knowing all the keys of all the windows...

jcgeny,

Would this be a better question posed to Microsoft? Especially since you're looking to find information about the registry keys for TCP/IP and the different Windows releases.

Hi and sorry for hijacking your topic.

I am trying to start a discussion but when I click "post message" I get the error message "Access to this place or content is restricted. If you think this is a mistake, please contact your administrator or the person who directed you here." This happens after I wrote the whole post. Can someone please give me a hint what to do?

@Michael : it is the way the forum is managed . it happened to me too , i had an email few hours after my post .

@john : i do not know that M$ has a forum like this one . sometimes i visit msfn but there are no M$ people there .

my question is also very specific to cpu : xeon , chipset and network . my idea was that you are very used with these settings in particular and answer would be quick .

my question is relative to windows 8 and i want to set

NetDMA State : disabled

Direct Cache Access (DCA) : disabled

enabled .

itried method that were ok with win7 , but win 8 "updated" the way to get the same so it no longers work as i know

thank you in advance

jcgeny,

Microsoft does, in fact many of them. See the http://social.microsoft.com/Forums/is/categories Microsoft > Forums Home.

may be i ll try , this one looks very young because it has few topics , half of them answered...

that is not a so good result .

i would prefer a wiki about the windows and for each of them : the registry with all keys and all settings they can have according to software and hardware . as well as all others files having settings like hosts ....
