Thanks, Egor. For interest, I'd also point to a talk by Ian Ozsvald I attended at PyconUK in which he covered his take on the soup of tools and techniques used to squeeze extra performance out of Python ( http://www.slideshare.net/PyData/high-performance-python-landscape-ian-ozsvald). The talks were videoed (sp) so a video might be available soon.
