Slow assetbundle unload

Hi,

I sometimes get a massive frame drop when i call Assetbundle.Unload(true). It is not always it happens. I used Unity’s profiler and it always shows it is when calling Assetbundle.Unload(true). Is there anyone who have an idea what could cause this? Also the assetbundles are not very big in size.

Any help is appreciated.

Thanks,
Martin

unload true means that it must kill all objects and assets out of this asset bundle.
if you came up with the idea to load a scene with 1000 objects or 100mb size thats something to expect for example
