Slow remote connection speed/performance

Symptoms

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

Possible causes and solutions

Remote Utilities is outdated or version mismatch

Remote Utilities is improved with each version release. Using the latest version to date is highly recommended. You can download it on this page.

When you update Remote Utilities make sure that Viewer and Host/Agent are the same version. Version mismatch between Viewer and Host/Agent may lead to performance issues and some features not working.

Internet connection slow

The overall speed and performance are only as good as the slowest network segment between Viewer and Host. Even if there is a broadband hi-speed Internet connection on the Viewer side, a slow 3G or GPRS connection on the Host side will lower performance regardless of Host CPU power.

Direct connection vs. Internet ID connection

A direct connection is faster than an Internet-ID connection. 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.

Default Internet-ID server vs. Self-hosted server

If you use Internet-ID connection you can make it faster by using self-hosted server (RU Server) instead of our company's public servers. Learn how to set up Internet-ID with RU Server.

High color depth

If remote connection is lagging, try decreasing the color depth to 8 or even 4 bits. To change the color depth, navigate to the Color and CPU section in connection properties and set the color depth to a desired value.

Visual effects

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

Economy mode

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.

Low-end or outdated CPU

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.

High CPU load

If you are running Remote Utilities on a computer where almost 99% of the CPU capacity are used by other programs or processes, the program's performance may be slow. Remote Utilities needs CPU resources just like any other program.

You can tweak CPU usage in connection properties. Navigate to Color and CPU 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.

Screen capture mode

Sometimes, changing the default screen capture mode can help:

  1. On the Host side right-click the Host icon in the system tray and select Settings for Host.
  2. Navigate to Other and enable Use legacy capture mode.
  3. Right-click on the Host icon and select Restart Host or simply restart the Host PC.
