There are a few networking performance features added to Windows Server 2022.
Let's take a look at some of them.
UDP Segmentation Offload, or USO. This moves most of the work
required to send UDP packets away from the CPU and into the
network adapter specialized hardware, making this a lot faster.
TCP HyStart++ reduces packet loss during connection startup, and if you have a
high speed network, this is going to improve performance quite a bit. TCP RACK
reduces retransmit timeouts, and both of these features are enabled in the
transport stack by default to provide a smoother network data flow and improve
performance. And as mentioned,
Hyper‑V switches are a lot faster because of receive segment
coalescing. The last network performance, Azure extended network,
where you can actually take your on‑premises private IP addresses and
move that subnet to Microsoft Azure.
So essentially, it all looks like the same network; however, they are
separated by a tunnel from your on‑premises up to Microsoft Azure. I
hope you've enjoyed this short course on just the changes to Windows
Server 2022 and this has helped you make a decision whether to upgrade
to this new operating system, and if you do upgrade to the new
operating system,
you know what changes have taken effect. I very much appreciate you taking this course.
