We are playing the mod with Space Exploration and some other Mods and we are experiencing FPS drops when we connect to many Item I/0 Busses. Also the second Slot for Filter is bugged. We can only use the first one

Yes, I am very much aware of that and I'm trying to make it more optimized rn. But there is only so much I can optimize since the games api for moving items an fluid between chests and tanks is in of itself is not load friendly.

Also the second filter slot is going to be fixed next update.
