ULightHost Performance: 2vCPU 4GB+ for Windows OS, 1vCPU 1GB for Windows 2012 or earlier

Dear SurferCloud Users,

We would like to address an important issue that has been brought to our attention through recent customer feedback and support reports regarding the performance of Windows operating systems (OS) running on our ULightHost instances. Several users have reported significant performance issues, including lag and slowdowns, particularly when using the 1vCPU 1GB RAM configuration with Windows OS. This has led to an increase in customer complaints and after-sales support requests, and we want to ensure a smoother experience for all our users.

Recommended Configurations for Windows OS

To ensure that your ULightHost instance runs efficiently and without performance issues when using Windows OS, we recommend the following configurations:

1. For optimal performance:
   • We highly recommend selecting at least 2 vCPU and 4GB of RAM when running Windows OS on ULightHost. This configuration provides a better balance between CPU power and memory, ensuring that Windows runs smoothly and without noticeable lag.
2. For users who must choose 1vCPU 1GB configuration:
   • If you opt for the 1vCPU 1GB configuration, we suggest installing Windows Server 2012 or earlier versions. Windows OS, especially newer versions, can consume a significant amount of memory, and with only 1GB of RAM, the system can become unresponsive or slow. Versions like Windows Server 2022 or newer may cause performance bottlenecks on this configuration, and we strongly advise against using them.
3. Why avoid 1vCPU 1GB configurations with Windows OS:
   • Windows operating systems naturally require more memory and processing power than many Linux distributions. When running on lower configurations, such as the 1vCPU 1GB setup, the system may not have enough resources to handle the demands of the OS, which results in a sluggish user experience. The limited memory and processing power in this configuration make it difficult for Windows to function optimally, particularly when running more resource-intensive applications or services.

Summary of Recommendations:

• Best Experience: For running Windows OS, please opt for a 2vCPU and 4GB RAM configuration or higher.
• If 1vCPU 1GB is necessary: We recommend installing Windows Server 2012 or earlier versions.
• Avoid using Windows Server 2022 or newer with the 1vCPU 1GB configuration.

We understand that each user's needs vary, and while we offer a range of configurations, it is important to choose the right one to meet the performance requirements of your applications and OS. By selecting the appropriate configuration for Windows OS, you can avoid performance issues, complaints, and the need for after-sales support.

Thank you for your understanding and cooperation. If you have any questions or need assistance in choosing the right configuration for your needs, our support team is always here to help.
