Every time the 'drawnow' command is called data is sent to gnuplot,
which is what's taking time. So what you want is to postpone calls to
'drawnow'. Now, before Octave waits for user input it calls 'drawnow'.
So, what you can do is either put your plotting commands in a script,
and then call that script from the command line. An alternative is to
enter all your plotting commands on one line, so instead of typing

  plot (bigdata)
  title (t)

you can write

  plot (bigdata) \
  title (t)
