Unity take a lot of time to process

Unity takes a lot of time to startup and when we click on an game object or anything in the editor the editor goes to hold loading UI and takes a lot of time. is there any solution for the problem or is it an unity error? i am using unity 2021.1.5f1.

The problem could just depend on the how old your computer is…

My computer spec is :

Intel(R) Core i7-2700k , 3.5GHZ
16GB ram
GeForce GTX 1060 6GB graphic card

an SSD or faster drive could make a big difference if you don’t have one.

if you do have one, make sure that your project is saved there.
