You're not really testing what you think you are testing. When you do "_ = load something", the compiler just throws away the load. You have to use the result somehow to keep the load in the final assembly. What you are actually timing is the speed of the modulo operator (%). For the pointer c

Syncthing's transfer model is a bit different with it's block-exchange protocol, so it's a bit difficult to compare the exact behavior. For most use cases, I think you'd see comparable performance in terms of data transfer required for change propagation, though Mutagen could perform a few add
