Using all logical processor in unity3d editor environment

Hi everyone,
I have a problem in unity3d editor side.

The scene I’m working with is a very intense scene made up of 3d models.
When I run the game in the editor environment, the computer uses only two of the 48 logical procces of the computer, but when I build the game and run the .Exe application, it uses all 48 proccessories.
This makes me very slow in the editorial environment.

What should I do for all 48 logical processors to work in the editor environment?

Does anyone have any idea?
