Issue description:

Performance issues with big auto crafting requests. The modpack I use is skyfactory 3.0.8.
https://i.shnig.de/z7ueT9

The CPU is a quad core Intel CPU running @ 2.40GHz.

Normally the server runs at around 40% load on a single core. With autocrafting of large quantities it raises to 100%.

What happens:

Lag and position reset ingame.

No lag.

Steps to reproduce:

1. Queue large amounts of autocrafting (~20.000)
2. Experience lag
