@heEXDe thank you for filling this. Mind providing bit more context, so we can route this to the right repository?

1. is the memory usage coming mostly from kubo daemon or Electron (Desktop app GUI)?
2. how long is your node running?
3. are you running with default Kubo configuration, or did you adjust things like Swarm.ConnMgr? The default should trim unused connections down to <100 when idle.

1. Most of the memory usage seems to come from Kubo itself (screenshot)

2. The node usually operates more than 5 hours a day

3. I don't recall making changes to the default settings. When idle (connections to fewer than 100 peers), the node doesn't use much less memory (the decrease is about 10%), that's part of the problem.
