In addition to serialization / de-serialization, there are other
overheads like ORB initialization, GIOP protocol overheads - including
message fragmentation if the data size is more than 4K, Object waits on
the socket listener thread etc. Did you try performance profiling the
client's VM to get more insight on where the time is being spent ?
