How to disable Vista's network throttling?

What your Giga network is doing in term of real File transfer.

I am not sure that the measure that you are using represent real functional Network capacity.

 
It doesn't seem to be limited to the type of data. I know for reasonably certain that my Gigabit network is capable of much much faster transfers. As a matter of fact, Vista forgets to throttle the network throughput once in a blue moon, and I was able to capture the moment.

As you can see, the transfer is capped at 6~7% most of the time (in this specific case it's more like 2~3%), but when it's not its performance increases by ten folds. Unfortunately it only happens 1 out of 100 transfers.. :frown: Basically the AT article echoes my experience but the fix suggested doesn't seem to work on my system.
 
I did read that article. 😉 But I thought the registry hack was supposed to bypass the throttling?

I am going to play with the values a little more. (never thought that I would try 255 but will give it a shot!)
 
One way to do fast evaluation of total functional Network read an d write file to the Hard Drive is y using a Disk Mark Program that can measure read and write through the Network to a Mapped Drive.

This free application does it, http://crystalmark.info/downlo...e.html#CrystalDiskMark

This picture shows the Disk Read/Write activity through a Giga Network.

Every thing was equal the only difference is that the measuring computer was one time working with Vista and second time with Vista SP1 (I use Mobile Rack to exchange Drives).

"M: Remote" (as seen in the pic.,) is a computer on the Network that its drive is mapped as M do the measuring computer.

Read means the Speed that the computer reads the Hard Drive through the Network from the remote computer's hard drive.

Write Means the Speed that the computer writs a 50MB file to the Hard Drive on the remote computer.

All computers.

IPv6, and Qos unchecked in the TCP/IP Properties.

TrenNet Giga switch, using regular Cat5e cables.

Measuring computer AMD x2 4400 939 onboard Gigs card.

Remote computer IP-35-E runing E2180 @ 3GHz using onboard Giga.

All HDs are Seagate 320G SATA 7200.10

Note: The above is just an example, and a frame of reference.

It is based on a 50MB file, different file sizes yields different result.
 
Thanks for the suggestion, Jack. I will do that as soon as I get a chance.

In the meantime, I toyed around the registry values on Vista 64bit and Vista 32bit systems (in the sig). By setting 80 on the 32bit system (quad-core) and setting 60 on 64bit system (dual-core) I was able to achieve 20~50% of network usage. Weird because I didn't get that performance when I set both @80.
