Based on that link I tried it as follows:

int const binary_archive_flags =
boost::archive::no_header | boost::archive::no_codecvt;

  filebuf fb;
  fb.open("ofile", ios_base::out);
  binary_oarchive oa(fb, binary_archive_flags);

  clock_t start(clock());
  oa << lst;
  clock_t end(clock());


I didn't discern any improvement to the performance of this 

test from adding those flags.

I don't see how that is relevant.
