Blender user interface 2.9

How do you speed up the User Interface in the latest version of blender? I honestly dont have a clue on how to make the speed of the User interface better for me because i keep getting “Not Responding” Errors when ever i do the most trivial of tasks in blender whether its just going to a different tab or changing a texture or even a tool… heck even saving a project i get the same error over and over. (Can Anyone please help me with this issue?)
