Plotting with 3.2.0 on Windows is SLOOOOOOWWWW

[Matthias Brennwald]

Dear all

Consider the following code:

-----------------

N = 100;

n = 2;

m = 2;

tic

for i = 1:n*m

    x = rand (2,N);

    subplot (n,m,i);

    plot (x(1,:),x(2,:)); 

end

toc

-----------------

Executing this with Octave 3.2.0 on my MacBook running on Mac OS X, the tic/toc timing reports about 0.06 seconds, and it takes about 1 second until all plots are displayed (using gnuplot). Doing the same on the same machine with Windows results in a tic/toc time of about 0.1 seconds, but the plots take more 5 minutes to appear.  The same happens on a 'real' Windows machine. I don't think this is how it should be, so I guess I might be doing something wrong.

I need to produce many such plots on a Windoze system. Is there anything I can do to speed things up?
