This is one of the mods I was talking about in my other post, that had issues. Most of the posts there mention broken saves, or saves that are slowed down due to unnecessary overhead. I think there is another multithreading mod somewhere that was a little better.

Updating this wouldn't be very easy because the author didn't use git properly. It's hard to see what exactly was changed from TPT because it isn't a fork. I think the "multithreading" here is not done very great either, I can already see in one of the commits that his fix for electronics was awful, and involved duplicating a few hundred lines of code. If you want to multithread TPT, that mod isn't using the proper method.
