Network Adapter and Driver Issues

One aspect that causes many performance problems is adapater and NIC compatability issues (full vs half duplex as an example. The document "Troubleshooting Cisco Catalyst Switches to NIC Compatibility Issues" from Cisco covers many vendor NICs.

Performance Impacts of Host Architecture

The host architecture has impact on performance especially with higher rates. Important factors include:

Performance-Friendly Adapter and Driver Features

There are several different techniques that enhance network performance by moving critical functions to the network adapter. Those techniques typically (but with the notable exception of GSO) require both special hardware support in the adapter and support at the device driver level to make use of that special hardware.
