> Message serialization in the native protocol currently make a Netty's ChannelBuffers.wrappedBuffer(). The rational was to avoid copying of the values bytes when such value are biggish. This has a cost however, especially with lots of small values, and as suggested in CASSANDRA-5422, this might well be a more common scenario for Cassandra, so let's consider directly serializing in a newly allocated buffer.
