performance issues

[JonasJurczok]

Hi,
I just added the mod to my map to replace robots.

I have 3 or 4 logistic networks. All except one are very small (10 roboports, 200 robots).
The biggest one has roughly 1k roboports and ~20k robots. Immediately without placing a chest the UPS dropped by 4.

After placing a chest the UPS stayed the same.

I therefore assume that the performance bottleneck is in the initial loop construct where you build a map of the existing networks.

Question: Do you think it is possible to persist the map between ticks?
Also the multiplication in the on tick event seems to be unnecessary, maybe this is also a small improvement.

What do you think?

An additional idea:
would it be possible to put filters on all roboports to deny landing of certain types of robots?
Then the AI pathfinding could do the job and redirect all robots to the only "free" roboport, which is the chest. (I don't know enough about the logistics API yet to make a PR on my own right now :/ )

Can you provide me your save do I can have a look for me the ups showed no changes but I am also not doing mega bases.

As for the second thing as I am not the original author and have not much exp with modding I don't think I can do it sry
