> The {{SSLEngine.wrap()}} method requires the provided buffer to be 'big enough' to contain any kind of *SSL/TLS* message. That means 16921 bytes. The way it's implemented is that we allocate such a buffer every time we need to call the {{wrap}}  method, then we copy the result into a smaller buffer that is injected into thee write queue.
> This is quite ineficient. It would rather be a better idea to use a Thread Local Storage buffer when calling the {{wrap}}  method, and copy the content into a temporary buffer.
> Another optimization could be to concatenate the successive calls to the {{wrap}} method into a single  buffer, that will be sent in one shot (it's frequent that more than one call to {{wrap}} is needed during the handshake).
