Track Overview
Performance & Mechanical Sympathy
Ensuring that an application performs at the expected level under differing loads is always a challenge for developers. This is made even more complex when balancing latency and throughput requirements against the cost of infrastructure or cloud.
In this track, we have presenters with deep knowledge of the best approaches to use to meet application performance goals. Discussions will cover both software techniques and how to work in sympathy with the underlying hardware to extract the most from it.
