Raspberry PI4 - high memory usage of teddycloud

Hello guys,
i installed 3 days ago the teddy cloud docker image, and im wondering, why it takes so much memory usage of the raspberry.

Other docker-images: 4.7% of Memory – 200 mb
Teddycloud docker image: 19,3 % of Memory - 800 mb

Is there a config i can adjust to have less memory usage, or could you check if docker-image can be impoved to consume less memory usage?

Thank you very much!
