I have huge lag spikes on big maps.
I host a space explo map with a big megabase and use the combinator to automatically request stuff that needs to be built on other planets.
The combinator are on relatively small Networks but the main base on Nauvis is huge.

I get a lag spike.
Every 4-5 sec the game freeze for 1 second completely then resume 1 sec after at 44 UPS for 1 more sec, then resume to normal.
Removing the mod fix the problem.
I noticed that as my network in Nauvis become bigger, the problem becomes more serious (drops from 44 to 33 UPS and increase the duration of the lag spike. )
There is No combinator in the big network in Nauvis, (at least I hope so)

Anyway to make it so that only the specific network in which the combinator is is scanned?

Bonus question, anyway to make it so it has more lines and is able to scan more items at the same time? (twice as much would be perfect.)
