I had always assumed that this is because the rebuilding code was written in Python. In fact this is not so! Although the yum-presto plugin is written in Python, it just calls out to the applydeltarpm program written in C (assuming I'm looking at the right place: https://gitorious.org/deltarpm/deltarpm). Has anyone analyzed why the rebuild step is slow? Seems like the best thing to do would be to make it faster if possible.
