Question: did you unmount/mount the source filesystem between tests? When the size of data is less than RAM you are measuring cache speed, not so much disk speed. (And yes I realize that you have SSDs.)

source filesystem was also ramfs for these.
That being said, I am quite confident the results are accurate and don't mind other people running their own tests.
