How can I improve networking performance on my Amazon EC2 Windows instance?

Last updated: 2020-11-13

I’m running an Amazon Elastic Compute Cloud (Amazon EC2) Windows instance. How can I take advantage of improved networking enhancements?

Short description

You can enable enhanced networking to achieve higher bandwidth, higher packet-per-second performance, and consistently lower latency. All current generation instance types except T2 instances support enhanced networking. Supported instance types use either the Elastic Network Adapter (ENA) or the Intel 82599 Virtual Function (VF) interface.

Resolution

For supported instance types, first determine the enhanced networking mechanism that is available for your instance type. Then, enable enhanced networking using the Elastic Network Adapter (ENA) or the Intel 82599 Virtual Function (VF) interface.

For T2 instances, and as a best practice for all instance types, be sure to upgrade AWS PV drivers on Windows Server.

Note: If the instance is a domain controller, upgrade AWS PV drivers on the domain controller.
