I have this lite Client-Server framework based on Blocking IO using

ObjectInputStream#readObject(...) I was wondering if anyone can
recommend a Serialization framework that would outperform the vanilla
Java default Serialization?
But you will be transmitting data via a format that omits the object
graph overhead and focuses on just the data to share. The object-graph
knowledge is coded into the application and need not be transferred.
XML is awesome for this kind of task.
http://www.json.org/ might also be a good alternative which - depending
on format etc. - can be less verbose. See http://json.org/example.html
JSON is convenient for JavaScript heads, it is not human readable,
this is one reason why XML exists in the first place.
I am not sure why you say JSON is not human readable while XML is.
Remember: for network transfer you would use the most compressed format
of either which means that for XML you would not have line breaks and
indentation. I'd say an XML on one line with a reasonable complex
structure is not human readable.
JSON was
a mistake, instead of coming up with an arcane hacked syntax
to replace XML; JavaScript should have been improved to handle
XML.
That sounds like opinion to me. Can you provide any real arguments why
XML should be chosen for as a data transfer format over JSON?
XML does have some overhead and often uses more bytes to represent the
same structure.
There's also an interesting discussion at stackoverflow:
