You can not disable nagling just making a regkey do disable it.
You need to activate QoS on Vista because QoS is disable by default.
Go to Start/Control Panel/ Programs and Features...
Now on your left side you see Turn Windows Features
On or Off after that just active Microsoft Message Queue (MSMQ) Server
[you need to active all be under that MSMQ file by clicking on +].
Now you can disable nagling happy tweak guys xD

QoS is enable by default in windows vista, because autotuning technology is based under Qos. There are about fifty articles in microsoft technet about it. read some of them

EDIT: No one can disable nagle algorithm, unless u r a kernel substractive layer programming. U can modiefying some parameters yes, like philip describes in his article, but if u at last find a way to disable it, the results of tcp/ip is for fun. nothing works

I don't MSMQ has anything to do with QoS.
MSMQ is efficient way to send messages between processes or computers. We use it a lot in our corporate enviroment.

Sir just a quick question, why is it every time I click on the Vista Patch link it directs me to this page with these written on it. It won't let me save it or download anything to my desktop.

Click the link with your right mouse button and choose "save link as" or "save target as".

**babolgam** · 04-26-09, 11:25 PM

yeah that's what I did but it opens as a notepad and when I tried opening it with cmd nothing happens. Sorry for being a noob. hehe..

When the file is open in notepad, click file -> save as..

Select Save as type to All files (*.*) and save it as patch.cmd, not patch.cmd.txt or anything.

Hi everyone,

I am having serious broadband issues so I signed up to the forum and have been running through some of the tweaks.

I have ran the TCPOptimizer and the SG_Vista_TcpIP_Patch.cmd. I am on Virgin Media's XL package in the UK (which boasts a 20MB line) and got the following results.

Receive-Side Scaling State : enabled
Chimney Offload State : enabled
Receive Window Auto-Tuning Level : disabled (have previously tried normal)
Add-On Congestion Control Provider : ctcp
ECN Capability : disabled
RFC 1323 Timestamps : disabled

This seems to have improved load times on web pages but since running the tweaks my download speeds have not improved and in some cases have gotten worse (in a few case not budging from 0kb/sec from a reliable server)

I'm thinking this has something to do with my RWIN value being way too low.

Any advice will be GREATLY appreciated.

Well your MTU is WAY too low and so is your RWIN. Go here: http://www.speedguide.net/read_articles.php?id=2574

And follow what it says.

Hey guys,

I'm new to this forum and I was wondering if I could get some feedback on my connect speed. I used the TCP Analyzer and this is what I got:

The vista patch does the same in vista and in windows 7

**100 010 00** · 12-11-09, 09:38 AM

Philip....., just for win7 and 2008, u can add in patch the NetDMA 2.0, which adds support for Direct Cache Access (DCA)
two ways.........

netsh int tcp set global dca=enabled
[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters]
EnableDCA=1

I was wondering how you set that thanks for the information. I looked it for it when 7 was still beta couldn't find it.

**100 010 00** · 12-11-09, 12:16 PM

i think it is leaked now via internet, just google it. i think that Intel is the researcher of this technology.

I saw the intel part of it a while back it did seem like at the time intel was going to make cards/software to fuly utilize that feature thouh I'll re read it again though.

**100 010 00** · 12-12-09, 06:14 AM

btw, enabling dca, internet is running smoothly and especially browsing it seems like you have stored all the webpages in your hard drive and everything runs so quickly, because the response times are 2 low, cause of not using the memory for these operations and the data are being tranfered directly to the CPU . DCA is futuring technology and that means the end of ram's life in a while, but u need latest cpu's for that.
