Very high memory usage

Steps to reproduce

I've been having issues with Suwayomi using rather insane amount of memory. Limiting it to 512MB is causing it to break with errors due to being out of heap. This is with a library of just 150 manga's. Only once I increase this to 750MB does it run normally again.

I understand this is Java and it's a bit memory hungry. But requiring the memory equivalent of 4 sonarr instances feels like a bug.

Expected behavior

I expect this application to take about 200MB memory, if not less, for small libraries.

Actual behavior

It constantly throws exceptions if I give it anything less than 750MB
