Not any worse than 'dd' would be more than acceptable. How can anything be faster at physically moving data than dd as it is usually only slowed by the speed of the storage in any case? Slower, (to a reasonable degree) than dd would even be acceptable if it's atomic and online like existing pvmove of real LVs since it being online means nobody is sitting around waiting for it. So it can be slower even (again, to a reasonable degree).
