Remote Desktop Gateway performance

Question

I currently have a remote desktop gateway running on Windows 2016. When we push greater than 350 megabits of traffic we start experiencing severe lag and some users are dropped from their RDP session. I have plenty of bandwidth with 700 megabits available and I've ruled out performance problems on the firewall. The numbers of users on the server is generally around 80. CPU utilization at high load times is 20% and RAM consumed never exceeds 1.5 GB which a total of 8 available. I do see in the httperr log several request_cancelled lines.

Hello @Dennis Poore

1. Did this happen only after you installed RD gateway on the server?
2. How are RDS roles distributed ?
3. Does this affect internal or external user?
4. Have you tired uncheck "Bypass RD Gateway server for local addresses" from RD client?

Here is an article for your reference:

1. We only see the performance impact through the RDP gateway.
2. Users remote into their individual workstations so the only role is the gateway on a Windows 2016 server, no brokers.
3. Internal users are not using RDP.
4. Yes.

The article you reference really doesn't apply as all the tweaks are for RPC. Everything is going through TCP and UDP.
