> 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(..).
