Hi,

Please find the benchmark code and results attached. It compares
serialization of devector/batch_deque/std::vector/std::deque. (I couldn't
find a ready serializer for Boost.Container). The comparison is not exactly
fair, because it seems boost/serialization/vector.hpp also adds version
information. Measurement was done as above.
