[2.0.60] Logistics Manager cratering my UPS with relatively few logibots

I've setup my Fulgora base in a way that it uses 3000 logistics bots to manage scrap recycling and science production. However, when running the base my UPS/FPS drops to ~30 solely due to the logistics manager using 20ms of processing power. I have an i7 11400f Intel CPU so I am not sure why it's struggling so much.

I've attached my save for replication. I'm unsure if this is an issue with a mod I'm using or an issue with the logistics manager itself.

“relatively few logibots”

I find that performance goes down anytime there are more than 1000 Bots per network, or when bots are trying to pick up “1 item at a time” because they cannot find a Stack of items. It also scales poorly with more Logistic chests (more inventories to be evaluated).

From your screenshot, it looks like your Scrap Recyclers are directly feeding chests - this is almost guaranteed to only allow 1 item of each type at a time to be stacked before a bot is dispatched - wasting 3/4 of the bots carrying capacity, and thus requiring 4X as many bots for the same throughput!


Try pre-sorting the scrap output into specific Chests for each output type. Good Luck!

This is due to the usage of active provider chests and every single robot that takes items from the active provider chests trying to condense them into the same few sets of storage chests. The robot queue logic falls short in this scenario and the game tries too hard to find a "better" robot than simply waiting for one to be free.

I have an idea that might improve performance slightly but I'll have to experiment with it and see what side effects it has.

In the meantime, the underlying issue is you need more robots.

There were idle logistics bots in the network when I took this screenshot. Not sure how many since I redid scrap handling but I don't think more bots would've solved the issue in this case.
