Fast Object Serialization with Jackson (json), Aalto (xml)
More interesting performance benchmarking:
Looks like Aalto
is not the only thing that serializes objects to text very fast: Jackson
does some ultra-sonic processing as well!
It will be interesting to see how the other side (deserialization, ie. parsing) performs: my experiences suggest that this is where Jackson+json really shines (as well as Aalto, relative to sjsxp). But it is good to know that even serialization is faster with these 2 libraries than with any other textual alternative, bar none.
