Assuming the amount of data to be transferred if fairly large,
buffering at each stage has benefits, as it reduces the overhead at
that stage. True, the operating system has its own buffers, but your
internal routines could still very well be the bottleneck in getting
the data to the operating system's buffers.

You won't know for sure unless you _do_ test it yourself. There's no
practical way to predict ahead of time how buffering is going to
affect any specific situation.
