Issue description:

Using Colossal Chest(12M) as External Storage. When shift-crafting stack(s) it causes immense TPS lag. It does not matter what is crafted, but the more items in the recipe the worse and longer the TPS lag.

What happens:

TPS lag

What you expected to happen:

Fluffy bunnies?

Steps to reproduce:

1. Craft and set up a colossal chest
2. Fill it with items and attach external storage to interface
3. Shift-craft something with items from the chest
   ...

Version (Make sure you are on the latest version before reporting):

• Minecraft: 1.10.2
• Forge: 12.18.3.2202
• Refined Storage: 1.2.16

Does this issue occur on a server? [yes/no]
Unknown, tested SSP.

I believe you briefly mentioned issues with Colossal Chest in Darkosto's stream raoul, but after a quick search here I cannot find any mention of it. So just to be sure, reporting.

Occurs on server as well.

WarmRoast:

Related to CyclopsMC/CyclopsCore#35, it is related to a very slow construction of capabilities

This also happens with storage drawer controllers and any other kind of large storage system.

Without nps files of the issue we can't really do anything. So feel free to profile it and make an issue for it.

can you expand the warmroast view a bit more so we can see which item is causing the stack copying lag?

Tbh 5% seems rather low @raoulvdberge, I wonder where the other time is going if that is the issue.

I need to change the ext storage a bit so it doesn't uses copies of stacks, since it only does comparing in detectChanges. I'll look into that later.
