Developing for speed: minimizing app latency at scale - Next '17

You know that latency matters. Lower latency correlates to an increase in user engagement, sales and user satisfaction. In this session, we'll talk about sources of latency, how to investigate it (including benchmarking, profiling and tracing), how to minimize it and how to approach application design and make architectural decisions with latency in mind.
