Do C# static functions perform better than nonstatic functions, beyond reduced memory usage?

Question

I assume that public or private static targets must have reduced memory usage, due to the fact that there is only one copy of the static t

Answer 1

Aside from what astander said, your question suggests a misunderstanding of what instance methods do. Regardless of whether the function is static or not, there is only one copy of the function code in memory. A non-static method has to be called through an object, but the object does not carry its own private copy of the method. So the memory usage of static and non-static methods is in fact identical, and as others have pointed out, the performance characteristics are nearly identical.

Non-static member variables, however, do exist separately for every object that you create. But it is nearly always a waste of time to worry about that memory usage, unless you actually have a memory-related problem in your program.
