    Performance Tuning for Networking


    The network architecture covers many components, interfaces, and protocols; Figure 1 illustrates some of them. The sections below discuss tuning guidelines for some of the components for server workloads.

    The network architecture is layered, and the layers can be broadly divided into:



    • The network driver and NDIS. These are the lowest layers. NDIS exposes interfaces for the driver below it and for the layers above it; for example, TCP/IP.

    • The protocol stack. This implements protocols such as TCP/IP and UDP/IP. These layers expose the TDI interface for layers above them.

    • System Drivers. These are typically TDI clients and expose interfaces to user-mode applications. The WinSock interface is exposed by Afd.sys.

    • User-mode applications.

    Tuning for network-intensive workloads can involve tuning for each of the layers. Some of the tunings are described below.
