[2.1.14] Large quantities of items with equipment grids cause significant lag

[Izzabelle]

I was told to report this on behalf of several others, not even sure myself if it qualifies as a bug but anyhow;

If large amounts of items with equipment grids such as modular armor or above is created, the electric network ms usage spikes due to the equipment grids being simulated even when empty. This can practically never happen in vanilla or space age but I can imagine some mods could be affected by this.

Game updates on a fresh save with 600 000 Power Armor MK2 with empty grids on belts in 2.1.

Attaching the relevant save for testing. It's just mk2 armor on express belts.

Thanks for the report however this is not a bug. This is simply how equipment grids work at the moment.

This being how stuff currently works absolutely doesn't mean it's not erroneous behavior. Empty equipment grids, with neither power generators or consumers have zero reason to have a power network be simulated for them.

In fact, this is the "no producers or consumers, network not simulated, early-exit" case. The always-simulate version is much slower.

Just wanted to mention that this is a real case a user had, he was bussing armor with equipment grids and his electric network update time ended up being several ms. That being said, just hitting that point took ~29,000 armor items on belts so it is an edge case of an edge case.
