How to Enhance RDP Performance
Symptom
RDP users have performance issues (bad user experience).
For example:
Mouse is lagging
Screen is building up very slow
Session uses high bandwidth
Several other performance issues
Problem
There are many different causes that can result in bad performance.
Solution
The following settings can be used as a single option and also in combination.
Basics
The color depth should be the same on the server, the device, and in the session (best: 32 bit).
In the BIOS, set the VGA shared memory to 64 MB or more.
Optimizations for a LAN Environment
Under Sessions > RDP > RDP Global > Performance, edit the settings as follows:
Disable Compression. (Increases performance, generates about 30% more traffic)
If RemoteFX 8 is available, activate Enable RemoteFX.
If RemoteFX 8 is available, set RemoteFX codec mode to "Optimized for LAN".
If Windows Server 2012 R2 or lower or Windows 8.1 or lower is used: Under Sessions > RDP > RDP Global > Multimedia, activate Enable Video Redirection.
Optimization for a WAN Environment
Under Sessions > RDP > RDP Global > Performance, edit the settings as follows:
Enable Compression. (Generates about 30% less traffic, consumes more local resources)
If RemoteFX 8 is available, activate Enable RemoteFX.
If RemoteFX 8 is available, set RemoteFX codec mode to "Optimized for WAN".
