Slow remote connection speed/performance


You can connect to a remote PC in the Full Control and View mode, but the connection is slow.

Possible causes and solutions

The overall speed and performance are only as good as the slowest network segment between Viewer and Host. For example, if there is a broadband hi-speed Internet connection on the Viewer side, and a slow 3G or even GPRS connection on the Host side, the speed and performance of the remote session may be slow regardless of the CPU power.

By definition, a direct point-to-point connection is faster than an Internet ID connection - the latter always goes through a routing server. Whenever possible, connect directly to a remote PC. If the remote PC is behind a router, it is still possible to connect directly using the port forwarding technique.

You can make your Internet-ID connection faster if you use a self-hosted server instead of our company's default ID server.

The default color depth is set to 16 bits. If the connection is lagging, try to decrease the color depth to 8 or 4 bits and see if it resolves the issue. To change the color depth, navigate to the Color and CPU section in connection properties and set the color depth to a desired value.

To improve performance, you can disable Windows Aero and turn off the wallpaper on the remote screen. Navigate to the Additional properties and enable Disable Aero and Remove wallpaper checkboxes.

Enabling "Economy mode" can improve performance in certain circumstances. To turn on Economode, navigate to the Network tab in connection properties and enable Economy mode.

Although there are no special hardware requirements for Remote Utilities, you need to run the software on a relatively modern PC with enough CPU power and RAM.

If the Host and/or Viewer are running on a computer with almost 99% of the CPU capacity used by other programs or processes all the time, then Remote Utilities performance may be slow. CPU resources must be allocated to Remote Utilities just like any other program.

You can tweak the CPU load in connection properties. Navigate to the Color and CPU tab and set CPU Usage to a lower level. If you want to manually set FPS (frames per second), move the slider to the FPS mark first and then select a desired number in the drop down list.

In some cases changing the default screen capture mode/algorithm can help:

  1. On the Host side right-click the Host icon in the system tray and select Settings for Host.
  2. Click Settings for Host and select Options from the menu.
  3. On the General tab enable the Use legacy capture mode option. Click OK and close the settings window.
  4. Right-click on the Host icon and select Restart Host or simply restart the remote PC.
