also you could try

ar & make_nvp("data", binary_object(sizeof(mpData), & mpData))

the cost of xml archiving is going to dominate even if you were to use
the default serialization method whch loops over every pixel.  XML
just has a lot of extra characters and requires parsing - it has to be
much slower then a binary format.
