I thought, using classes may require too much memory, because

Is my assumptions that in this case struct are more wise?
Yes, by all means use struct.
What would generate the fastest code for a cross-product for
example?
If you are on x86, SSE 4.1 introduced an instruction called DPPS
which performs a dot product. Maybe you can force it into doing a
cross-product with clever swizzles and masks.
