Hardware questions

Ok here are some questions i have about my mouse and key board.

My key board is a.
microsoft comfort curve keyboard 2000

I like it works well and last one i had lasted me 15 years be for i bought this newer one.
This is not wireless.

My mouse is a wireless.
logitech mouse M215

Works very well long battery life.

Ok my questions are pretty much the same for both.

I have been noticing that when i watch my task manager in the cpu usage my mouse can spike from 1% to 4or 5% when i use both at the same time i can see that my mouse and keyboard use about 10%

Any way to get these two to use very little cpu.I do not think i have ever seen mouse and keyboard ever use that much.
