I am happy that you found my suggestion useful! Given that the current savez implementation first writes temporary arrays to disk and then copies them from their temporary location to the zipfile, one might argue that this is what causes the buffers to be flushed, since it does more IO than the save implementation. Then again I don't really now the gory details of the how the filesystem buffers behave and how they can be configured. best, V- _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
