Having a comprehensive knowledge of different abstraction layers of a system allows the engineer to make right performance optimization where it makes most sense. This lecture will cover different layers of system where performance opportunities are present. The audience will learn that often changes at the right level can dramatically improve performance without significant engineering cost. I will share many examples along with concepts to highlight real world performance opportunities. All the examples were taken from real performance optimization that I have done over the past years. </div> <div class="row lecture__section"> <h2>About this Lecture</h2> <span> <strong>Number of
