Chunk is super laggy (please help)

[etron_mortron36]

So i was working on project red and was starting on a chest system and it broke when i took an item out. There is a video of it.  Now the chunk makes the server unplayable but wont crash it. I tried breaking all the pipes and chests and that didn't work. Aswell as i tried updating the missing blocks by tossing cloud in a bottles but nothing helps. Anyone know a way to fix it?

Its funny really, because this hasn't got anything to do with the storage system. Its not even connected. Just some basic transport pipes and junction pipes. I don't see any routed interface pipes connected to chests.
