[erlang-questions] gen_tcp/ssl send function and large binaries, should I split?

Hi all,

Actually when I send a large binary I split it chunk of 64MB and loop until
the end:


    send(<<Data:65536000/binary, Rest/binary >>, Transport, Socket) ->
        Transport:send(Socket, Data);
    send(Data, Transport, Socket) ->
        Transport:send(Socket, Data).


But I wonder if it's really useful, Does gen_tcp:semd and ssl:send take
care about it? Should I just use `Transport:send(Socket, Data)` ?
