Ask HN: Faster and most compact serialization tecnology?

What is the most compact and faster seralization/deserialization technology for transmit data over the network? Google Protocol Buffers, Message Pack, Thrift, Avro, ASN.1 PER I'm looking for a binary format, with fast des/serialization, avoid redundand data (i.e. including the name of the fields like JSON/BSON does) and most compact serialized data. I'll be using this for a multiplayer game, so it should be used to serialize few fields, but frequently. I'm also thinking a high performance way of processing this data. I'm considering Nagatti (based on Netty and implemented in Scala) Akka (Actors framework in Scala) I've also read about Norbert, but I'm not sure it would be necessary. I mean, I don't necessarily see the benefits of using ZooKeeper/JGroups in this project.
