No, but in the console messages, you'll find something like
> 7335600 dezicycles in test, 1 runs, 0 skips
> 4843950 dezicycles in test, 2 runs, 0 skips
> 3897100 dezicycles in test, 4 runs, 0 skips
> 3104525 dezicycles in test, 8 runs, 0 skips
> 2438056 dezicycles in test, 16 runs, 0 skips
> 2159306 dezicycles in test, 32 runs, 0 skips
that is related to the time of the byteswap conversion.
