The size you observed is the physical size of the file which is different from the logical size of the file. The difference is usually OS-dependent. In your case, the logical size of the file should be 64 bytes, but the physical size is 4KB on Mac and 12KB on linux. So these numbers make sense. I am not sure if there is anything we can do to make the physical size smaller.
