Enabling Receive Side Scaling
Applies To: Windows Server 2008 R2
To enable receive-side scaling, you need to enable it in the operating system and in the network adapter driver properties for each network adapter you want to enable. Receive-side scaling is enabled by default in Windows Server 2008 and Windows Server 2008 R2.

To open an elevated Command Prompt window, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type netsh interface tcp set global rss=enabled and then press ENTER.
Close the Command Prompt window.
