Rendering Slows down - After Effect 22 with Video Copilot Element 3D

First of all: I have a strong PC 64GB Ram. AMD Ryzon Threadripper, NVIDIA Quadro M4000. I was talking with the support an i cleand my System vom all Adobe Products with CCleaner from Adobe and intalled new. We did everything, we can do.

What happens is: If i use the render Queure, i can see how much Frames it renders per secound. 
Beginung with about 4 Frames per Secound antil 0,26 Frames per Secound after one hour. 

I saw, that the Concurrent frames rendering goes from about 10 Frames to 32 Frames. Average frame Time: 3,39s after a view hours.

The Material is solo a 3D Studio in a slow motion - 3 Minutes. And took 5 hours to render.

I use: Mercury Software Only in Video Rendering.

does anyone know the problem? Is it possible to set how many frames should be rendered at once, as I imagine this process slows everything down?
Does this have anything to do with Video Copilot?
In general I notice this effect that the render time is extended backwards also with other projects.
I appreciate any suggestions and ideas. Thanks a lot!

Correct answer Mylenium

Complex GPU plug-ins like E3D never work will with parallel rendering. It's an inherent limitation in how in particular OpenGL works as an exclusive client-based rendering model. You may have 32 CPU cores, but even on the most beefy GPUs you can still only run a much lower number of virtual driver instances. And that likely is the point: By using MFR you are forcing constant load and unload procedures and multiple calls in the render pipeline. Likely things work much better if you just turn off MFR.

Thank you Mylenium,
I'm celebrating. This is exactly where the mistake was. After I switched it off, it runs smoothly again. The rendering takes a lot of time but remains constant. 3D Element can be opened without errors again. Switching off the MFR was the solution. However, I think it was good to clean up the system once.
Thanks again
