AssetBundle.LoadFromFile/LoadFromFileAsync same memory usage as UnityWebRequestAssetBundle?

[Zapan15]

Hi,

We are using our own caching system for downloaded assetbundles.

From the blog:

Learn to save memory usage by improving the way you use AssetBundles

AssetBundle.LoadFromFile() and AssetBundle.LoadFromFileAsync() always use the memory cache for LZMA AssetBundles. We therefore recommend using the UnityWebRequestAssetBundle API instead.

From the docs:
https://docs.unity3d.com/2020.1/Documentation/ScriptReference/Networking.UnityWebRequestAssetBundle.GetAssetBundle.html:

Note, that while you can use this API to load Asset Bundle from local storage (using file:// URI or jar:file// on Android), this is not recommended, use AssetBundle.LoadFromFileAsync instead.

So the final question:
Would the memory usage ok (e.g. using a ring buffer or the like) when using AssetBundle.LoadFromFileAsync or AssetBundle.LoadFromFile when using BuildAssetBundleOptions.ChunkBasedCompression or BuildAssetBundleOptions.UncompressedAssetBundle or, should we always use UnityWebRequestAssetBundle for that to have the best memory usage?

Thank you.

Regards
André
