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