binary yade::serialization was faster than xml, I was using it for
that reason for few years. Though the speed difference was IIRC only
about 2 or 3 times faster.

boost::serialization in binary is more than 10 or 20 times faster.
I was loading and saving the same data in both formats, when doing snow
stuff. Apparently the only tradeoff is the compilation time...
