Shouldn't. It's lightweight as possible, no tick hooking, just permission requests

Very based, exact question I was about to ask.

im getting lag spikes every 1~2 seconds up to 750ms in a dev quick test map for this patch

StorageUpperBound.PatchHelper:Postfix

I was testing compatibility with this mod list:

[Mod list length: 11]

Stack gap [https:// no link (local mod)]
Stockpile Stack Limit (Continued) [https://steamcommunity.com/sharedfiles/filedetails/?id=2274678322]

I had 1 stockpile with:
Limit similar stacks set to 5
multi stack enabled for the stockpile, (set to per stockpile in settings)
Edit: Same issue with globally disabled

everything else set to default values as far as i know

same result without "Stockpile Stack Limit (Continued)"

Edit:

getting spikes up to 1400 ms with this list still:

Any news ?

The latest update contains more optimizations than before. Potentially making the optimization better than it is now does not seem possible
