Chances are that if you work in software, you spend time building applications. Between features, deadlines and bug fixes, it's easy to move performance to be ""nice to have"". But what do you do when user interactions drop off, and users start complaining? Instead of having a traditional, reactive approach to performance — what if we could be proactive instead? What if we could monitor performance continuously, and make informed decisions on which issues to tackle. In this talk, I would like to focus on continuous performance monitoring to tell a story of user interactions. We will look into working with Performance API in your environment, and give you simple methods to tell and read a story of your transactions. We will specifically take a look at creating timings, working with observers, and tracking transactions from frontend to backend.
