Python scales quite fine actually (Disqus and YouTube use it for a majority of core development). It's all about the tech behind the scenes (uWSGI, Tornado, Ngnix, memcache/redis, etc), not the language itself (just as it is with PHP). Try scaling PHP if only using Apache Prefork instead of mod worker + php-fpm or Ngnix + php-fpm and you'll see what I mean. I have no problem with using either PHP or Python on a particular project, depending on what is involved. I wish PHP threads would show a bit more maturity/pragmatism on both sides of the aisle sometimes. http://yougov.github.io/pycon/slides/ http://yougov.github.io/pycon/slides/ http://highscalability.com/blog/2012/3/26/7-years-of-youtube-scalability-lessons-in-30-minutes.html http://highscalability.com/blog/2012/3/26/7-years-of-youtube... http://www.slideshare.net/jinaljhaveri/scaling-python-webapps-from-0-to-50-million-users-a-topdown-approach http://www.slideshare.net/jinaljhaveri/scaling-python-webapp... http://blog.disqus.com/post/62187806135/scaling-django-to-8-billion-page-views http://blog.disqus.com/post/62187806135/scaling-django-to-8-...
