Never trust a benchmark you didn't run yourself. A realistic Genshi template is butt slow. More than a handful function calls per byte emitted is not uncommon

Never trust a benchmark you didn't run yourself. A realistic Genshi template is butt slow. More than a handful function calls per byte emitted is not uncommon. Regarding Django it become a lot slower when they introduced automatic escaping and loop item unpacking a while ago. I have seen many people switching from Django templates to Jinja2 especially because of the increased performance.
