Ever since 1.16.100 to 1.17.10.20 Beta this still has been an issue (Affected version are only 1.16.221 Hotfix and 1.17.10.20 Beta because it doesn't show me other versions). Worlds load/generate for more than 2 minutes and my CPU usage reaches 80-100% when worlds are loading/generating.
Steps to Reproduce:
1.Enter or create a world
2.Wait for it to load resource packs
3.Observe loading/generating speed or observe CPU usage
Expected Results:
Worlds loads/generates in less than 30 seconds and CPU usage less than 80-100%
Observed Results:
Worlds loads/generates slowly and CPU usage reaches 80-100%
Edit: The two photos are in 1.16.200.57 Beta but this happens in 1.16.100-1.17.10.20 Beta so it's fine.
