RDP Latency IS Now Trackable in Windows Server 2012
Several weeks ago, I gave a really fun talk at BriForum about the hidden benefits found inside Version 8 of the Remote Desktop Protocol – specifically, the fact that for any given RDP 8 connections to a Windows Server 2012 (or Windows 8) system, you can now track things like session latency, data throughput, assessed bandwidth, error rates, and much more. Provided you know which performance counters to query and how to query them.
The big catch here is not on the client side – you can get Windows 7 updated to use RDP Version 8, and Windows 8 and Windows 10 already run it natively. Plus, most thin clients (the good ones anyway) now support RDP 8.
No, the challenge is on the server side. Each week I talk to evaluators of our tools and ask them what server platform they’re running. Inevitably, the majority seem to answer Windows 2008 R2. Yes, I get it. Windows 2008 still gives you that nice Start Menu that your users know and love. But, to be frank, RDP Version 7 (which is what Windows 2008 uses) stinks when compared to RDP 8.
Why is Version 8 So Awesome For Higher RDP Latency Connections?
Two words: UDP transport. Yep, Microsoft’s RDS gurus REALLY did things right in RDP 8. By default, unless you disable it intentionally or unintentionally (more on that in a later blog article), RDP 8 uses both TCP AND UDP to serve up remote desktops to your clients. I won’t bore you to tears with the internal mechanics, but the key takeaway is this – on marginal, high latency connections (e.g. spotty Wifi, 4G mobile hotspots, overseas WAN links, or satellite), adaptive UDP transport overcomes much of the inherent “guaranteed delivery” limitations of TCP. In doing so, it effectively can increase data throughput from 3x to 10x over previous RDP versions, all while improving the responsiveness experienced by clients interacting with their sessions.
So Beyond Improved RDP Throughput and Responsiveness, Why Should I Upgrade to Windows 2012 Server?
Good question. Because once you do, you can use our software to track every aspect of network connection quality between your RDS servers and your client sessions, whether you want to do it in realtime, or via leveraging the ever expanding set of reports we’re creating. Seriously, what we can do with this information is awesome – it lets you, the admin, get in front of those annoying damn calls from users kvetching about how the connection is dropping, or their screen updates are too slow – etc. See for yourself by watching this video we just recorded showing these features in action:
That is really awesome stuff. And I have some Windows 2012 servers already deployed. How can I get a copy of your software to profile my users’ RDP latency and connection quality?
That’s super easy – simply start a monthly subscription of our Remote Desktop Commander Suite for only $9 per server per month. For this extremely affordable monthly rate, you can track RDP latency, RDP bandwidth consumption, CPU and memory consumption by session, plus review detailed session recordings for root cause RDS performance problem analysis and/or terminal server user auditing.
We haven’t rolled on Windows Server 2012 yet. We may wait for Windows Server 2016 next year. Is there anything in the meantime we can do to get some of this information?
Absolutely. Stand up at least one Windows Server 2012 instance in your farm, populate it with the same apps/desktop environments your users need, and then send your “problem children” clients directly over to the Windows 2012 server. If you do that, you can use our software to keep tabs on their connection quality, PLUS they’ll be able to leverage the awesome UDP transport offered by RDP 8.
