Tornado vs Yii: What are the differences?
What is Tornado? A Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.
What is Yii? A high-performance PHP framework best for developing Web 2.0 applications. Yii comes with: MVC, DAO/ActiveRecord, I18N/L10N, caching, authentication and role-based access control, scaffolding, testing, etc. It can reduce your development time significantly.
Tornado and Yii can be primarily classified as "Frameworks (Full Stack)" tools.
"Open source" is the top reason why over 34 developers like Tornado, while over 36 developers mention "Open source" as the leading cause for choosing Yii.
