Async operations?

there's folia but you cant use that unless you have a really large core count cpu.
just stay with paper and optimize it more

would purpur help out more? Not speaking from an async perspective but more in optimization configs?

cpus got 12 cores rn but i saw the recommended being 16

find some documentation on what you need

idk muc

This is the wrong question to ask and it's also an X/Y question.

What are you attempting to solve to begin with?

purpur on 1.21.5 wont perform better than paper

basically
