If true, then we send a standard SendMessage packet, followed by n MessageContinuation packets which contains the rest of the message split into each packet. | I'm doing this with a slightly variant. SessionSendMessage creates the ServerMessageImpl, and decode/encodes directly from the Buffer to avoid copy and get some performance. As SessionSendMessage is the class responsible for creating the MessageImpl, I was have a little difficult on instantiating the ServerMessage that will store the body on a file. Because of that, when using LargeMessages I'm using another PacketType to deal with Large Messages. With that the regular use case would be optimized avoiding extra non necessary copies. I will commit it tomorrow (on trunk or another branch) and it will be easier to talk about this later when I have some code to show the differences.
