I just realized that no one has created an issue for the crafting lag that was introduced when the crafting speed was changed in 1.6.12.

Issue description:

Tps lag when crafting with lots of crafting CPU's

What happens:

TPS goes down to 2.

Steps to reproduce:

1. Make Reborn Storage Autocrafter. (Mine is Max size 16x16x16 with 1 crafting storage the rest are cpus).
2. Setup pattern for Sextuple compressed cobblestone.
3. Connect creative drawer with cobble.
4. Request 2 Sextuple compressed Cobblestone (Anything more gets caught by the complexity check for me)

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

• Minecraft:1.12.2
• Forge:2815
• Refined Storage:1.6.14

Does this issue occur on a server? [yes/no]yes

Looking at that this might be on reborn Storage? Not sure if he can fix this with the current API but I will post on his git too.

That looks like the monitor is updating on every change instead of periodically. Related to #2132

Thanks, I will look into this when I have time.

Got a similar issue. Server tries to kill itself when you send a huge processing load through (e.g. 55,000 orders).

If a crafter is pointed to a machine or chest with a processing recipe, and that machine or chest fills up while an extreme number of orders are in the backlog, the server pretty much kills itself.

This is a separate Issue @Theyoungster I had 0 machines involved in this. If you could do some profiling and post another issue that would be great.

Alright. I suspect it's heavily related, but I'll post as a separate issue.

My issue is mostly fixed in this TechReborn/RebornStorage#149

Not sure if there are other things that can be done without changing how the crafting code works.
