    Hello!

    Over the past year I've seen the memory usage of the ResourceManager section on our project grow from ~20MB to 37MB currently. In order to find improvement opportunities I'm trying to better understand what contributes to its size, but unfortunately I couldn't find much info on this.

    Would it be possible to share some details on what impacts this native memory size? I'm not sure if this object is related to addressables metadata, Unity's Resources file mapping, both or something completely different like low level memory allocation management.

    Some context: this snapshot was taken on an Android player, built on Unity 2021.3.18f1 as a development build and taken with memory profiler package version 0.7.1.

    As always, thanks a lot for your wonderful work on this package!

    ResourceManager manages the default Player resources shipped with Unity ("unity default resources" file).
    Did you notice it grow when updating Unity versions?

    extra piece of information - ResourceManager is indeed also responsible for mapping all assets in Resources folder and their dependencies. So it may also grow if you have a lot of assets with interdependencies
