Here's an example setup for those confused about basic PI setup post incursion. There's not a lot of info out there, but here's the basic idea. Notice that I don't have links from each processor to the spaceport (spaceport is in the middle, and acts as my storage container). You can save power/cpu by keeping your links short, and in this case that means the extractor (to the left) has to link to both processors (the orange circles second from the left), but then the bottom processor links up to the top one. This lets me use the underutilized link between the top processor and the spaceport to push all of my processed goods through and lets me get more extractor head out instead of longer links between my devices.

You'll also notice on the right side a link running from the extractor directly to the spaceport. This was because I ran out of power for an extra processor and links, so I'm just pushing the leftover raw materials (it's not much, but money is money) back to the spaceport. The downside of this is the raw product takes up a LOT more space than the P1 refined product (in this case I'm turning P0 level noble gas into P1 level Oxygen). But since I use a freighter to haul my products to my hub to sell I don't care about this extra space being used up, so I get to use an extra extractor head instead of a processor. Gas planets in particular really suck up the power when you use links between your processors/extractors/spaceport, so be as efficient as possible (I could actually move the bottom left processor closer to the extractor and shorten it's link there while maintaining the same link size between it and the top processor if I wanted to eek out every little bit of efficiency).
