I have had good experiences with trees of maps and lists containing primitive types, serialized by json-lib. The same trees are easy to serialize using the apache xml-rpc libraries, and appear to stack-up reasonably well underload. Its not sophisticated, but it is fast to work with, light on the GC under load and appears to perform well.
