App is extremly slowing down with big cache (media exchange)

We have the problem, that if we exchange many pictures or videos in a room, the app cache grows and grows. After a size of 1-2 GB the app gets really slow and sending message is delayed for 2-4 seconds.
Clearing the cache makes the app fast again, but if the cache grows again, it gets more and more unresponsive.

It is hard to reproduce after cleaning the cache.

Maybe it is related to:
