In this new post to his blog Wojciech Sznapka compares three different frameworks - Symfony2 (PHP), Django (Python) and Ruby on Rails (Ruby) - in their request handling performance, lines of code and average community on Github.
If you ask me, which one is the best - I can't point one, all of them are very good. But let's try to measure frameworks. For purpose of this article, I created three applications in Symfony2, Django and Ruby On Rails. All those apps do the same - show two tables, one shows top USA cities (by population), second shows US states with highest number of big cities (above 100k citizens). I don't want to measure frameworks by echoing "Hello world", because it's pointless.
Each of his applications use the same data set and use a default ORM with optimized queries, HTML rendered by an internal template engine and rounded floats. His performance requests (using Apache's ab) for this sample application show Symfony2 being able to handle the most requests/second followed by Ruby then Django. Symfony2 comes in at a larger file size than both the others combined, though. As far as the community is concerned, Ruby on Rails outpaces the others with about three times as many "watchers" on Github.
Be sure to read the comments for some opinions, both for and against his results.
