Improve RDP performance by Specifying RDP Transport Protocol Preference


RDP performance can be greatly improved by removing the time it take to acknowledge the transfer and receipt of data when connecting to Hosted applications over the internet using RDP. By default, RDP connections are first established using TCP and transmit session data via TCP as well. You can change this behavior by modifying or creating a registry key:
  1. Launch the Registry Editor (Press Win+R, type regedit, press enter)
  2. Navigate to the path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services

  3. Locate the REG_DWORD key SelectTransport
    1. If the value doesn't exist, you can create it by:
      1. Right-clicking the free space
      2. Mouseover New
      3. DWORD (32-bit) Value 

      4. Name: SelectTransport
      5. Value: 2
  4. Double-Click the name to modify the key
  5. Change the Value to 2

  6. Click OK
  7. Reboot the machine
After the reboot, your machine will establish the RDP session using UDP and session data will prefer UDP.
