Hey. I just did some changes and now (after the restart) am i have extreme lag spikes due to this mod. would be nice if you could fix that.

ps: you can copy it by triple clicking the text. it works, even if you cant see the entire thing..

Because the feature of spoilage result for different qualities levels are controlled by runtime script, so more the items in the save, the more lag it causes.
I have done some performance optimization in 0.1.1/0.2.1 hopefully it works better, I also tested Krastorio 2 and QualityPlus mods that were enabled in your config, I haven't see significant lag spikes for large group of items.
I also added adjustable scanning interval, you can set it large to get more performance, but it will cause spoilage result to be delayed.
