The distributors, make sure they are equal/more than the belt speed for max efficiency

I'm constantly upgrading belts, distributors and tunnels, but HUB receiving 20/s and that's it.

Maybe try compact combiners (forgot the name, havent played in so long)

@WhoGotVectored You got the name one- *chrome extension shows updates*

You got the name one word off. The name is compact merger.

Oh, wait don't use balancers those suck because they take up twice as much space as compact mergers and splitters. And if you're playing Shapez Industries, balancers can take up to four times the space as smart balancers! (4x with 3 inputs, 2x otherwise)
