[StrangePan][2.0.21] SegmentedUnit very high CPU usage

[Sopel]

SegmentedUnit at 1ms/tick for me. Asked someone else, they don't have it at all. I think it's some bug. Attaching a save.

Although I'm not sure exactly, I think it has something to do with the demolishers on Vulcanus. After loading a few saves, the entities labeled as SegmentedUnit and SmokeWIthTrigger only appear after landing on Vulcanus. Loading in new demolisher territories, these values increase very fast.



Before loading new chunks, SegmentedUnit was using 1.1 ms and SmokeWithTrigger using 0.37 ms.

And After loading new chunks, SegmentedUnit shot up to 3.7 ms and SmokeWithTrigger at 1.22 ms.

After running this kill all command,

/c local surface=game.player.surface
for key, entity in pairs(surface.find_entities_filtered({force="enemy"})) do
entity.destroy()
end

The usage dropped nearly down to zero. Although, SegmentedUnit is still at 0.42 ms because I don't think the command kills demolishers that are in unloaded chunks. In the screenshot, you can see spaces where there's still territories.

I do believe this is a bug as it's pretty unreasonable for demolishers to be using this much processing power just to roam around in their territories.

Yes, it is due to demolishers, that's why I have a mod that kills them, as a workaround to this problem. I should have been clearer, sorry.

Code: Select all

    local big_demolisher = data.raw["segmented-unit"]["big-demolisher"]
    local medium_demolisher = data.raw["segmented-unit"]["medium-demolisher"]
    local small_demolisher = data.raw["segmented-unit"]["small-demolisher"]
    big_demolisher.max_health = 1
    big_demolisher.healing_per_tick = -1
    medium_demolisher.max_health = 1
    medium_demolisher.healing_per_tick = -1
    small_demolisher.max_health = 1
    small_demolisher.healing_per_tick = -1

I don't see anything concerning SegmentedUnit in that thread, though yes, it's related.

Demolishers are segmented units.

I'm also facing this problem. I have low FPS when connecting to a multiplayer server. FPS seems to tank when using lots of bots, but I also have 4ms SegmentedUnit and 1ms SmokeWithTrigger that's just constant. The menu says I have 153 segmented units active.

Can upload map if necessary. My friend who lives closer to the server is not having FPS issues but still sees the 4ms SegmentedUnit costs.

Once the fix for this one is live and your issue persists, make a new report following 68653 please.

[manishearth]

Thank you! Will do; do you have an estimate on which release I should be waiting for?

[manishearth]

Ah, I can just watch the release logs for issue 120275, that works, thanks!

same thing for me. wanted to make a thread but found this after looking up segmented unit.

I'm playing a game with an acquaintance.

We swap save files and host the saves on either computer, depending on who starts first.
Up until a few days back, either person could host the game without issue.
Now it's asymmetric.

If I'm hosting, he can play with no ups slowdown. He says his ups are at 60.

If he is hosting, the game that I can run at 56 ups drops down to 5.6 ups.

Screenshot with time usage attached.

[Musil]

We fixed the performance issue for us using this admin tool and hiding explored parts of the map. Segmented unit time use went from 6 ms to 0.09.

Looking forward to this fix - I was really surprised when I checked time usage and it had gone up a ton after exploring for a while on Volcanus. SegemntedUnit is taking up 2.5ms

as someone who never modded before, can you please explain how do i use this?

you need to make a data-stage mod
