File Transfer in RDP Session Is Slow

Slow file transfers in RDP sessions can be caused by multiple reasons, such as the inherent RDP protocol design and how file transfers are handled within the PrivX architecture:

• RDP protocol limitations: The RDP protocol was not designed with high-performance file transfer in mind. This is the primary cause of slowness.
• PrivX server extra hop: When transferring files in PrivX, the files are first copied to the PrivX server, then relayed to the destination. This double transfer introduces latency in both directions.
• 3rd-party component constraints: Transfer may be faster in one direction, but slower in another. Investigations indicate this may be related to the memory allocation strategy of a third-party component integrated with PrivX.

Potential Solution

For transferring large files in Windows environments, we recommend using SSH Tectia Server instead of RDP-based file transfer.
