There are a few networking performance features added to Windows Server 2022.

2
00:00:06,560 --> 00:00:08,270
Let's take a look at some of them.

3
00:00:08,270 --> 00:00:14,840
UDP Segmentation Offload, or USO. This moves most of the work

4
00:00:14,840 --> 00:00:19,500
required to send UDP packets away from the CPU and into the

5
00:00:19,500 --> 00:00:24,460
network adapter specialized hardware, making this a lot faster.

6
00:00:24,460 --> 00:00:31,210
TCP HyStart++ reduces packet loss during connection startup, and if you have a

7
00:00:31,210 --> 00:00:36,230
high speed network, this is going to improve performance quite a bit. TCP RACK

8
00:00:36,230 --> 00:00:41,320
reduces retransmit timeouts, and both of these features are enabled in the

9
00:00:41,320 --> 00:00:47,070
transport stack by default to provide a smoother network data flow and improve

10
00:00:47,070 --> 00:00:49,320
performance. And as mentioned,

11
00:00:49,320 --> 00:00:53,710
Hyper‑V switches are a lot faster because of receive segment

12
00:00:53,710 --> 00:00:59,040
coalescing. The last network performance, Azure extended network,

13
00:00:59,040 --> 00:01:05,110
where you can actually take your on‑premises private IP addresses and

14
00:01:05,110 --> 00:01:07,890
move that subnet to Microsoft Azure.

15
00:01:07,890 --> 00:01:12,690
So essentially, it all looks like the same network; however, they are

16
00:01:12,690 --> 00:01:18,690
separated by a tunnel from your on‑premises up to Microsoft Azure. I

17
00:01:18,690 --> 00:01:22,080
hope you've enjoyed this short course on just the changes to Windows

18
00:01:22,080 --> 00:01:27,960
Server 2022 and this has helped you make a decision whether to upgrade

19
00:01:27,960 --> 00:01:31,200
to this new operating system, and if you do upgrade to the new

20
00:01:31,200 --> 00:01:32,340
operating system,

21
00:01:32,340 --> 00:01:39,000
you know what changes have taken effect. I very much appreciate you taking this course.
