Time To First Tweet
When users come to Twitter.com, the first thing they want to do is read their timeline. The time that it takes for a user to do this formed the backbone of our performance improvements that are currently being rolled out. We'll explain how we measure Time To First Tweet, how we re-engineered our front end to make this as fast as possible and what our next steps will be to improve our user's experience. Through this we can demonstrate that a pragmatic approach to web performance can help you make the biggest positive impact on your users experience.
