Vista Broadband Autotune Features

Hi All,

As I've been enjoying Vista a LOT, I was looking in the Vista Tweaks section on Speedguide.net & found that MS Vista's new TCP IP stack has the ability to autotune broadband internet connections due to packet load and or router capabilities/defiencies (much like a "gamer" would be trying to do w/ proggies like TCP Optimizer) except that Vista can do this on the fly while you're surfing, playing MMOG's, etc. Speedguide noted that in Vista this is usually turned off by default but in Server 2008 this is turned on by default.

Hmmmm............................................Now why would Redmond do that? I can understand why turning this on for server usage but I'm a big time online gamer & this ability caught my attention--do y'all know what it means to have a stable connection when you're in the middle of a big intense furball w/ a LOT of others trying to shoot you down? This kind of usage is very much like a server being pinged by LOTS of users trying to get their presentations, budgets, timesheets, projects, etc & IT checking the server as well because Joe can't get his presentation files to run off PowerPoint cause the server is too busy so they're in there checking for malicious "content" that may be using up needed resources............................you get the idea.

So I went in & checked thru "elevated command prompt" & sure enough it was turned off. So I just went in & enabled it & set all up according to Speedguide's recommendations to see what Autotuning would do.............................

All I can tell you is this:

If you do a lot of online gaming you will WANT this on!

Check it out at SpeedGuide.net :: Broadband · Cable · DSL · VoIP · Security · Network Tools

I posted this here as I couldn't find any references to this tidbit here in this forum.

Now if you just only surf the 'net & online shopping & such I really wouldn't bother w/ this as Vista's TCP IP stack in default configuration is more than enough.

Hence why I posted this in the Gaming section.

:)

Ummm, from that page:

The default auto-tuning level is "normal"....

I think you meant

By default, Vista has CTCP turned off, and Server 2008 turned on.
Click to expand...
Also, to enable the TCP Chimney Offload state, use

Code: 
netsh int tcp set global chimney=enabled
and to enable the Receive-Side Scaling use

Code: 
netsh int tcp set global chimney=enabled
Since the article does not mention *how* to enable those two.

*Hint: copy the above commands in the code boxes, then right click your elevated CMD prompt and select paste - then you won't have to worry about typographical errors.

No worries - just wanted to make sure that most people understood what was default and what was not.

That, plus the fact that that article never actually gives you the commands to set the last two options - almost as if someone removed them....

How much of a speed increase would you actually get from doing this?
This is what most users will want to know before changing any settings.

I discovered recently that some of the stuff like Recieve Side Scaling are handled by the Intel Gigabit Lan adapter, if running a motherboard made by Intel. I checked the properties for the Gigabit Lan adapter on my motherboard and discovered this.
