 It is not fair to compare the performance of those two methods, since
 a serialization process is much more complex than just copying some
 doubles into a byte array. In any case, it is worth to review the
 serializer and see if we can use the Buffer bulk copy methods.

+Not fair? What will you say for this? ;)

+We really need high speed serialization/deserialization mechanisms 
+of base types for our programs (HPC)... Otherwise we'll have to 
+write our own serializers... But I don't want to do it, cause I 
+think that we shouldn't reinvent "bycicle" ;)
