Why is This One Tiny Blue Box Causing Your Factorio Bottleneck?
Why is This One Tiny Blue Box Causing Your Factorio Bottleneck?
Small changes in late game often wreck throughput. Players notice lag and item backup suddenly. Why is This One Tiny Blue Box Causing Your Factorio Bottleneck? hits when belts stall.
That Little Blue Box Is a Filter Circuit
Why is This One Tiny Blue Box Causing Your Factorio Bottleneck? is a filter circuit inside a chest. It lets only one item type pass. Studies indicate this micro gate can choke line speed fast.
How It Slows Your Whole Line
When circuit conditions block output, inserters pause. Neighbors wait, and queues pile up behind that chest. Research shows timing signals right keeps belts flowing.
Use splitter-side filters to keep items moving.
Why is This One Tiny Blue Box Causing Your Factorio Bottleneck? Are Variants Causing Queues
This behavior also appears with constant combinator setups. Similar signal logic applies to arithmetic combinators checking color.
Q: How do I stop chest filter lag? A: Place filters on splitter output, not main bus, and keep signal logic simple.
Q: Will inserters slow even with zero pollution? A: Yes, paused inserters from bad filter logic happen regardless of game speed settings.
