Hi Dave!
In my test case I read LOB of 10 megabytes size.
So then in the function (with 4kB SOCK_BUFFER_SIZE):
SOCK_get_next_byte(SocketClass *self)
below line (socket.c):
self->buffer_filled_in = recv(self->socket, (char *) self->buffer_in,
self->buffer_size, 0);
runs in the following schema: 0msec, 200msec, 0msec, 200msec... etc.
So above times suggest delayed ACK timer (200msec).
