Maybe I'm missing something, but there doesn't seem to be a benchmark that measures the 2to3 performance, supporting the claim that it runs "two orders of magnitude" slower (which I'd interpret as a factor of 100). My Jinja2+Werkzeug's testsuite combined takes 2 seconds to run (Werkzeug actually takes 3 because it pauses for two seconds in a cache expiration test). 2to3 takes 45 seconds to run. And those are small code bases (15K lines combined).

It's not exactly two orders of magnitude so I will probably change the writing to "just" 20 times slower but it illustrates the point.
