Hi!
We are currently updating our Intouch 2012 (v10.5 and v10.6) and Intouch 2014 (v11.1) to Intouch 2017 (v17.3).
We were using workstations as nodes and WinServer2012 as NAD server, with centralized DAS (v10.5 & v10.6). Now, we are using HP ThinClient as nodes, and two WinServer2016 (with load balancing) as NAD/DAS server (v17.3).
We are exposed to very poor performances with both Intouch Maker & Viewer (at least 40% slower than workstations).
I did many tests, like getting more RAM and/or CPUs. It didn't help significantly. I also try to disable firewall, anti-virus, defender, etc. I even tried a empty WinServer2016 OS (I mean, only Windows). I also made a VMWare WinServer2016 machine hosting on a PC (instead of network infrastructure).
While I was doing my tests, I noticed that the problem disappears if the RDS (Remote Desktop Service) is disable, and reappears as soon as RDS is enable. Since I got 15 clients, spread in 2 servers with load balancing, I can't let RDS disable.
Wonderware is investigating the problem for 4 months now, and didn't come with a solution.
I search a lot on internet, tried some technotes, posts, etc. Nothing!
Hope you guys can help us !!!
P.S. I already tried what described in those topics
