Why Does My HPE ProLiant DL380 Gen10 Server Running Windows Server 2022 Require Real-Time Priority for Applications, Unlike My Windows Server 2019 Setup?

After deploying a new HPE ProLiant DL380 Gen10 Server with Windows Server 2022, which is equipped with 2 CPUs, 48 cores, and 96 threads, we noticed that certain applications are significantly slower unless we manually set their priority to Realtime in Task Manager. This issue does not occur on a similar application running on a different server with 20 cores and 48 threads using Windows Server 2019, where the application runs smoothly without requiring manual priority adjustment.

Despite performing several optimizations—including setting the power options to High Performance, disabling core parking, and enabling Static High Performance Mode in iLO—the problem persists.

What could be the underlying cause of this issue, and how can we resolve it so that we don’t need to manually set the priority to Realtime every time? Could this be related to hardware configuration, software settings, or resource allocation, and what steps can we take to ensure the application runs optimally without additional manual intervention?

    Hello,

    Thank you for posting in Microsoft Community forum.

    Based on the description, I understand your question is related to windows Server.

    Ensure that all drivers and firmware for your HPE ProLiant DL380 Gen10 Server are up to date. This includes BIOS, iLO, and any other relevant firmware updates. Make sure that your Windows Server 2022 installation is fully updated with the latest patches and updates from Microsoft. Sometimes, performance issues are addressed in updates.

    You can try adjusting the CPU affinity for the applications in question. This can help ensure that the applications are running on the most optimal CPU cores.

    Some applications might have specific settings or configurations that need to be adjusted for optimal performance on Windows Server 2022. Check the documentation or support resources for the applications to see if there are any recommended settings.

    If the issue persists, consider reaching out to HPE support for further assistance. They might have additional insights or recommendations based on your specific hardware configuration.

    Have a nice day. 

    Best Regards,

    Molly
