Hello,
I am playing a game on this old laptop i monitor a lot so when i read "can improve performance by 10x or higher" i clicked the fork to try it out. I had the latest version( july 31rst) and several other mods too.
After few hours of normal gameplay i realized that most of the time machine was unusually spent on "chart update".

I deleted all radars and empty chunk on my map, no result. Even deleted all entity on nauvis using the editor no result.
I used a deconstruction planner to remove everything allowed inside all the factory ( conviently placed in the same surface), no result.
Only thing that worked for me : use editor and use the "remove all entity" option on the surface factory floor-1. ( This destroy the power transfer and probably other thing i can't tell).
To make sure i tested a on a new game with only Factorissimo 2 notnotmelon fork and placed several factory using /cheat all, and the "chart update"quickly climbed up :

(On your own test you may not see the number in ms as high, that's because of me using the old laptop)
All of this with the setting for "single surface" ticked on but on another new map I tested without the option for "single surface", with similar result .
I think there is a performance problem because this doesn't happen with the other Factorissimo, on a new map with same number of empty factory placed there is no noticeable time taken by the "chart update". ( which i only see this high relative to the other thing when you explore the map at very fast speed).
I can provide more information or save file if anything would be useful
