XDR.writeXxx(..) methods ultimately use the static XDR.append(..) for writing each data type. The static append creates a new array and copy data. Therefore, for a singe reply such as RpcAcceptedReply.voidReply(..), there are multiple array creations and array copies. For example, there are at least 6 array creations and array copies for RpcAcceptedReply.voidReply(..).
