So. my UPS for this save has been steadily at 10-15.
While the game is still playable (thanks Wube), the slowdown is still annoying.

And I'm not sure what causes it.
Is my factory too big /built wrong? (Then I will rebuild)
Am I doing something that is known to tank performance? (Then I will stop)
Too many planets and space platforms?
Circuit network / combinators?
Bad train system?
Something about bots?
Some mods using a lot of UPS?
Is my map too big / needs chunks trimming?
Or is my PC just potato?

I've tried to fix the problems by deleting like half the factory, most mods, and all space platforms. Yet the issue persisted.
I'd really like to find a way to make it run faster, at 30 UPS at least, so please help if possible.

Save file and logs included.
I believe all the mods can be downloaded from portal when save synced.

Looks like your base is just big. There's a lot of time spent updating entities, especially demolishers, but if you update to 2.0.33 that will be better. Projectiles are also unusually high with very high spikes. That could be created by a mod, maybe Ceres? Try removing that one and seeing how it affects your UPS.

Other than that you base is just too big for you PC. This you can see with inserters taking on average 4ms by itself, which is significant.

Should I try to minimize amount of inserters then?
Will loaders be better?

Btw can someone with better pc try running this save and report what ups they get?

For me, it runs at 45 UPS on my 12900K.

Ah, so maybe it's truly because my pc is a potato with fx-8350
