you might want to batch the writes you should get around 200-300
objects per write (under the 5 sec timeout)
and probably around 2k per request before hitting the 30sec request
timeout (all depends on the complexity of
your objects)

In JDO/JPA, you do this using owned relationships which is covered in my
