reddit never cared much about performance, they blame it on IO but they chose to use cassandra, they used it as a key value store, then they put python on top of it, with the result that most pages would take seconds to generate and the website would go down almost every day.

With the "new" reddit they replaced most of the frontend with javascript and it really shows. That's not to say I like sites that use too much javascript but python is slow enough just parsing and filling html templates, seemingly.
