Managing bandwidth effectively is crucial, especially on networks with limited capacity. RDP automatically adjusts settings based on bandwidth and round-trip time, but you can further optimize performance by tweaking specific configurations.

Here’s a quick guide to recommended settings:

You can apply these adjustments using Group Policy or PowerShell. For instance, to set a throttle rate on your session host, use the following PowerShell command:

New-NetQosPolicy -Name "RDP Shortpath for managed networks" -AppPathNameMatchCondition "svchost.exe" -IPProtocolMatchCondition UDP -IPSrcPortStartMatchCondition 3390 -IPSrcPortEndMatchCondition 3390 -ThrottleRateActionBitsPerSecond 10mb -NetworkProfile All

Set Up RDP-UDP

Adding UDP support alongside TCP can dramatically improve RDP performance. In fact, RDP over UDP can handle 2 to 8 times more data throughput compared to TCP.

To enable RDP-UDP:

• Open TCP and UDP port 3389 on your firewall.
• Adjust Group Policy settings to allow UDP connections.
• Verify the UDP connection status to confirm proper setup.

Configure QoS Settings

Quality of Service (QoS) prioritizes RDP traffic over less critical data, ensuring smoother performance. Microsoft suggests using a DSCP value of 46 (Expedited Forwarding) for RDP traffic.

Here’s how to implement QoS:

• Set Priority Levels: Use TCP port 3389 to create dedicated queues for RDP traffic, helping maintain steady performance even during high usage periods.
• Configure DSCP Markers: Assign DSCP markers to session hosts via Group Policy Objects, allowing network devices to recognize and prioritize RDP traffic.
• Enable RDP Shortpath: Activate RDP Shortpath for managed networks to ensure QoS policies are effectively enforced.

With these network optimizations in place, you’re ready to dive into refining client and server settings for even better RDP performance.
