Cloning large areas with clone commands have started to lag the game to extreme levels.
The same large clone commands that ran fine in 1.16 now easily have to the potential to keep the game frozen for several seconds or time out players on servers.
This may be an issue with 1.17 being overall poorly optimized and slower than previous versions
We do not have enough information to find the cause of this issue.
While the lag occurs, please run
/debug start, wait a while and then run/debug stopin order to create a debug profile. Afterwards, run/debug report.If you do not have the permission to run these commands, open your world to LAN and enable cheats. If you're on a server, make sure that you're a server operator in order to execute these commands.
Then, please attach the profile results found in
[minecraft/debug/profile-results-<DATE>.txt|https://minecrafthopper.net/help/finding-minecraft-data-folder/], as well as the debug report found in[minecraft/debug/debug-report-<DATE>.zip|https://minecrafthopper.net/help/finding-minecraft-data-folder/]here.This issue is being temporarily closed as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.
