Which is faster? passing parameters to function by reference or by itself (owner moving context)
Ther's no single answer. It depends on the size of the argument passed.
Does the location of data in memory changed in owner moving?
Theoretically yes, but it can often be optimized away.
"move" in Rust does not imply that any data is actually, physically, moved around in memory. "move" is a high level, conceptual, idea at compile time about who owns data. The owner is the one responsible for the destruction (deallocate, free) of the data when it is no long in use.

Heap allocations aren't moved, but the stack portion may need to be physically moved. As I said, it may be optimized away.
A function may well be compile to inline code. At which point nothing need be physically moved I presume.
Optimisers move in mysterious ways, their wonders to perform.
