Application performance is something that is expected, but rarely asked for, by users. Performance is easy to ignore until it is a problem. In this talk, I will demo a tool called MiniProfiler that provides real-time performance feedback during development. It can quickly reveal when and where performance issues arise. We will use feedback from MiniProfiler to get better insight into the bottlenecks in our application and improve its speed. Finally, we will explore how having simple, rapid profiling feedback affects our development process and how we could apply it to other areas.
