Question Empty scene is permanently allocated to native memory

Hello dear Unity Forum,

I'm in the early stages of my first game and not very familiar with memory management.

In order to be able to better evaluate the memory utilization, I installed the Memory Profiler, which now also shows me the allocated native memory.
Unfortunately, I had to realize that after a short time more and more memory was allocated.

I then downloaded version 2022.2.0b3.2730 and created an empty project (2D URP).

Even with a completely empty template with default settings, memory was permanently allocated.

You can see from the picture that it's a significant amount in a short amount of time.

Now to my actual question: Why is there such a pool at all and why is it getting bigger and bigger, even if nothing changes at all in the game scene?

Thank you in advance for your help!
