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?

Matthias
