You can't do this. You are combining pylab figure management (eg
figure) with explicit use of FigureCanvasAgg. Who the hell knows what
will happen.
If you want to use pylab, just create the figure as above and you can
access the cancas directly w/ fig.canvas and set your backend to Agg,
eg with
import matplotlib
matplotlib.use('Agg')
before importing pylab.
If you don't want to use pylab, follow the approach of
http://matplotlib.sf.net/examples/agg_oo.py
Note there we use matplotlib.figure.Figure to create the figure, not
pylab.figure.
This is probably your problem. If I were to guess, you are getting
caught up somewhere in some GUI nastiness inadvertently by using
pylab.figure and this is causing the slowdown.
