The only thing I could think of is that matplotlib.matplotlib_fname does:

    fname = os.path.join( os.getcwd(), 'matplotlibrc')
    if os.path.exists(fname): return fname

So if os.path.exists is slow for directories with many files, this
could be the culprit (though it would surprise me).

Maximilian, these lines are found in matplotlib/__init__.py -- you may
want to try commenting them out and rerunning to see if this helps
your issue.
