Slow RDS sessions
-
Not sure we have enough info/access yet to get to an answer but worth a try anyhow!
The company I work for has been bought recently and we are dealing with an infrastructure we aren't super familiar with just yet but have been tasked to help with the issue.
Branch offices access virtual desktop sessions hosted on a server at the HQ(NY).
One branch in our area (Denver) is having performance issues with their remote sessions. Performance is reportedly fine at the rest of the offices. We are by some margin the furthest away so I sort of suspect some kind of latency issue.
Everything in the remote session is laggy at this location. For example load a webpage with a photo slider at the top and each change ends up being drawn line by line.
There is a site to site VPN between the locations provided by SonicWALL devices.
Pings to edge devices and the server being accessed have so far seemed decent to good.
Have checked traffic on the internet connection and so far it doesn't look like they are over running the connection capability.
Also ran an RD session to a host in AWS West region which worked without trouble from the same location, internet, piece of hardware. Not sure this tells us a whole lot though since there is still a lot changed from one situation to the other.
What other steps can we take to find the issue and stamp it out?

Need to find out about any fine-tuning that may have been done to the RDS servers. These settings may work well for the other sites, but not the Denver site.
What are some of the ping times you are seeing from the Denver Site to HQ over the VPN?
-
Can you get actual latency numbers, both for Denver and some sites that are working well?

Not sure about this bit, will see what I can do. I think there is a load balancer involved as well which I could see being part of the issue.

That could easily do it, if it is breaking the streams.

Don't have numbers from other offices that are working will ask. From my desk, sub 50ms but this is a different Denver location(we are also slow when connecting to the RD server).
Probably able to get numbers from at least the actual problem site again a bit later today.

New info:
Some of our connection attempts have been run direct from my office to a server in the RD farm rather than through their standard method, sessions still exhibit slow behavior.
Neglected to bring my laptop when visiting that office earlier today. All of the staff there are on thin clients so any pings would have been inside the NY network.
Probably there is access to diagnostic tools on these devices but I didn't have time to find them. Need to poke at the manual.

Are the thin clients hardwired or wireless?
