Issue

Catalina is running fine as it, but when i try big sur i can hardly use it because it's too slow including cursor and window animation.
If this information can be helpful, It restarted few times while being installed. Tell me if you need additional logs or information.

This happens when spotlight starts indexing things on Big Sur during the installation. You can disable Spotlight and a reboot usually fixes the lag.

Thank you @sickcodes !
It works fine after disabling the spotlight indexing.
Closing issue.
