There are basically two reasons why you may experience slowness while using your virtual desktop:
- system overload;
- slow Internet connection and/or high latency.
Before you search for a solution, you need to understand which of the issues mentioned above is causing the slowness. In rare cases, you can have both!
You have a system overload when the CPU and RAM of your virtual desktop are not enough to sustain the tasks you are performing on it. When this happens, you can see high and steady CPU usage from the ubiDesktop dashboard or from a resource monitor (task manager) inside your virtual desktop.
To fix this problem, you can either reduce the load on your virtual desktop by decreasing the number of tasks in execution or upgrade your subscription to a higher plan so that you can have more CPU and RAM.
RDP/NX consumes CPU to stream the screen to your local PC or Tablet.
Slow Internet connection
If your internet connection is congested, you may experience slowness. In particular, when the latency between you and our network is high (>100ms), the responsiveness will be affected, and you may feel the lag when typing text or clicking on icons.
If you have low Internet bandwidth (<10Mbps) but the latency is ok, you may experience slowness when opening media content (audio, video, pictures) inside your virtual desktop.
To fix this problem, you need a better Internet connection, for example by increasing the signal quality if you are in WiFi or by limiting the traffic from other users (QoS).
If you can’t, you may reduce the resolution and the quality of the screen from the RDP/NX settings in order to save bandwidth.
