Importing and constructing points far away from origin (fast)

Hey, I´m importing georeferenced points that have xyz coordinates that are far away from the origin (see attached file). The creation of those points take 31 seconds (!) if I construct them with their “native” coordinates that are far away from the origin.

For testing I moved all of the points to the origin and reconstructed them at the new position. This reconstruction takes 2 seconds instead of 31 s. Obviously its better to create points around the origin. But how can I move those coordinates to the origin BEFORE creating them? What´s the math behind that? Thanks a lot!
