Preventing Windows from Decreasing Processor Speed during Remote Desktop Sessions for Scientific Workstations

Preventing Windows Decreasing Processor Speed in Remote Desktop Sessions on Scientific Workstations

Scientific workstations are powerful machines designed for resource-intensive tasks such as simulations, data analysis, and scientific computing. These workstations often run Windows 11 and are accessed remotely using Remote Desktop Protocol (RDP). However, users may notice a decrease in processor speed when accessing the workstation remotely compared to directly accessing the machine.

Understanding the Issue

The issue arises due to Windows' power-saving features, which reduce the processor speed to conserve energy when the machine is idle. When accessing the workstation remotely, Windows may incorrectly identify the workstation as idle, leading to a decrease in processor speed and an increase in simulation time.

Preventing Windows from Decreasing Processor Speed

To prevent Windows from decreasing the processor speed during remote desktop sessions, follow these steps:

1. Open the Remote Desktop Connection application.
2. Click on "Show Options" to expand the list of settings.
3. Click on the "Local Resources" tab.
4. Check the box next to "Settings" and then check the box next to "Apply Windows settings to remote desktop sessions" as shown in the image below:

This setting ensures that Windows applies the same power-saving settings to the remote desktop session as it does to the local machine.

Additional Tips

Here are some additional tips to improve the performance of remote desktop sessions on scientific workstations:

• Use a wired network connection instead of Wi-Fi for a more stable and faster connection.
• Close any unnecessary applications running on the remote workstation to free up resources.
• Use a remote desktop client that supports hardware acceleration, such as Microsoft's Remote Desktop Client or MobaXterm.
• Use a high-performance graphics card on the remote workstation and enable hardware acceleration in the remote desktop client to improve the performance of graphical applications.
