Description

Today i was using warmroast to figure out why my tps is going down and i had found this that may related to my issues, i highly believe it's AE2 that cause this issue anyways here is the picture

Environment

• Minecraft Version: 1.12.2
• AE2 Version: rv5-stable-9
• Forge Version: 1.12.2-14.23.2.2624

This is ultimately about dealing with NBT heavy items, which is not the fastest option. As well as other mods adding caps to random items, which in some way is designed to be slow and allow other mods to make it even worse without much effort.

On a first look, there seems to be a way to compensate it to some degree. But the underlying issue will still be around everywhere we cannot compensate for it. That is just how Forge wants it to behave.

Thanks you for a fast fix and quick reply <3

Still need to test some cases. The current implementation is still based on the earliest AE2 versions. So there might be or were some reason for the copy. E.g. to avoid issues with injecting more than 2B stacksize in a single operation. But there are no machines doing that and on first glance it would not even have prevent it.
