Hello again,
Sorry for this but my game is unplayable because galactic market mod takes 12-19ms for update (spikes up to 32ms). I dont know if you know what it means but the game is unplayable at 15/30fps. Please try to make it more UPS friendly.
Thank You <3

We can try but inherently this mod does a lot of things that take a lot of ups.

Can you post a screenshot of your base? how big is it? what are you doing?

Do you maybe have a discord where we can text normally? Mine is @mradik if you want to talk through it.

Also base is train-base, starting to go into the "megabase" stage, but still your mod takes more ms than every other mods together.
"What are you doing?" - standing still (1 autoseller + some power sellers)

try 0.3.6?
we'll try to profile it next week, maybe logs show what takes most ups. you're mostly selling power?

also do you have blueprint sandbox mod installed? (we saw a low of ups drain together with it)

no dont have any blueprint sandbox, but i found out why its eating so much UPS. you have no bucketing

yep try 0.3.6,we added bucketing for energy

This are the things i found are giving high UPS and their better value without changing or diminishing gameplay:

• L8423: script.on_nth_tick(1, process_fast_runtime_updates) → on_nth_tick(2) (or split: keep wallet/UI flush on 2, move hub/terminal calls to their own on_nth_tick)
• L7777: process_fast_runtime_updates — 8 sub-routines/tick → split per interval
• L6889: process_market_power_interfaces() — no bucketing → add 10 buckets, tick % 10
• L59: MARKET_HUB_PROCESS_INTERVAL = 5 → 15 (4 Hz instead of 12 Hz)
• L57: MARKET_TERMINAL_PROCESS_INTERVAL = 60 → 120 (every 2 s)
• L58: PERSONAL_MARKET_PROCESS_INTERVAL = 60 → 120
• L67: MARKET_SHARED_UI_REFRESH_INTERVAL = 60 → 30 only when dirty, else skip
• L7381–7391: refresh_market_hub_feeders — find_entities_filtered ×2 → MARKET_HUB_FEEDER_REFRESH_INTERVAL = 600 (10 s) and merge to one call with type = {"transport-belt","underground-belt","mining-drill"}
• L7673: refresh_market_hubs_near_entity — flags needs_feeder_refresh immediately → defer: entry.next_feeder_refresh_tick = math.min(entry.next_feeder_refresh_tick or math.huge, game.tick + 60)
• L6745: process_liquid_market_hub_bucket — get_fluid_contents + remove_fluid → keep at MARKET_HUB_PROCESS_INTERVAL, but raise to 15 with hubs
• L6568: process_market_terminal_bucket — build_inventory_item_count_maps per terminal → cache map per terminal, invalidate on on_player_main_inventory_changed / insert events; raise interval to 120
• L7741: reset_market_rate_label_rendering_if_needed — rendering.clear(script.mod_name) global → only clear/recreate the affected entry's render object, not all

Net effect (rough): per-tick Lua cost drops ~3–5×, max spikes drop from ~65 ms to <10 ms. Gameplay impact: invisible (sales/buys 2–4× slower in ticks, still sub-second).

Dont forget this is just my personal solution, your fix is your fix, cant force you into anything. <3

Will download to replace black market 2 mod when this is performant

try now, if latest changes made an impact on your save
