is it good to send request payload with extra information to spring controller

Please provide explanation whether it is good or bad?

For example
My DTO looks like

public class DTO {
private String code;
private String message;

getter setter .....
}

My spring controller end-point like

public final void controller( DTO dto ) throws Throwable {

}

Now when I call this end-point from client side I have sent

{
    code:"c1",
    message:"m1",
    t1:"t1",
    t2:"t2",
    t2:"t2",
}

Is it degrade performance at server side though t1,t2,t3 not mapped?

please explain in detail.

Thank you
