Python is a giant cache-miss generator. A little performance boost on the opt-code dispatch isn't going to change that much. If we really do care about improving python to do less environmental damage, then that is a discussion we should be having on it's own merits. It was really out of place, even in this tangenty thread. On 5/29/2015 20:34, Nick Coghlan wrote:

For performance patches we have to consider our responsibility for the environment. Every improvement means more speed and less power consumption. Python runs of hundreds of thousands of machines in the cloud. Python 2.7 will be used for at least half a decade, probably longer. Servers can be replaced with faster machines later and less fossil fuel must be burned to produce power.
Please keep your ideology out of this.
I'm a qualified engineer (in computer systems engineering), so caring about environmental sustainability is part of my professional ethical standards, not just a matter of personal preference: http://www.wfeo.org/ethics/
Given the power draw of large data centres, the environmental impact of performance improvements to the Python 2 series is a point well worth considering.
Cheers, Nick.
