Problems with Multi-Core and Dual-Processor PCs

Question

Hello, colleagues!

I would like to share the problem I encountered on my system running Windows 11 Enterprise and ask a few questions to find possible solutions.

System configuration:

• Processors: 2×Xeon 2696v3 ( 2699v3 the same )
• RAM: 128 GB (all 8 channels are used)
• Motherboard: Huananzhi x99-F8D Plus
• Operating system: Windows 11 Enterprise - latest updates

From a technical point of view, the build was performed correctly, no overheating was observed.

Detailed Information About My Equipment

Problem description:

1. Optimization of multi-core processors:

The system, apparently, does not distribute the load on multi-core processors efficiently. With two processors, the situation is aggravated.

2. Task manager limitations:

When trying to manually set the affinity for an application (for example, 3ds Max), an "access denied" error occurs. This does not allow you to correctly manage the thread loading.

3. Irrational distribution of processor resources:

Windows 11 does not always assign all available processors to one application, which negatively affects the management of computing resources.

4. An example of the Corona Renderer benchmark:

When I run Corona Benchmark, I see a strong drop in benchmark performance every 3-4 seconds. That is, the test is running and the threads are loaded at 100%, and then suddenly everything drops to 2-20%, and then rises again to 100% and so on ad infinitum.

Because of the above limitations, I have to use a third-party program Process Lasso to forcibly assign both processors to the desired application, although this only helps partially and only situationally. Previously, when working on Windows 10, the system was noticeably more responsive, even when the load on the processors reached 100%, which allowed other tasks to be performed in parallel. Now, during the rendering process, there are significant delays, which, as I understand, may be due to the peculiarities of NUMA and low GHz processors. BUT I remind you - there were performance issues on Windows 10, but not so obvious.

Questions to the community:

• Has anyone encountered a similar resource allocation problem in Windows 11 Enterprise, especially on dual-processor systems?
• Are there any recommendations or settings that allow you to optimize the distribution of the computing load without using third-party software?
• Could this situation be due to the peculiarities of NUMA or other hardware limitations, and how can this be compensated?
• Will Microsoft improve Windows optimization for multi-core and multi-processor systems?

I would be grateful for any advice and recommendations. Thank you for your attention!

Answer 1

Surprisingly, I have the same problems and the same observations with almost identical equipment. I have been looking for a solution to this issue for years and even flashed the BIOS to overclock my processor, but it practically did not help me. Thanks to the flashed BIOS, my computer became a little more responsive, but not much, unfortunately.

I am attaching information about the equipment. And you can see a drop here, when everything should work at 100%, but some of my flows dropped to 23%. This definitely shouldn't be the case.
