Fast by default- Algorithmic performance optimization in practice

We’ve learned to rely on sophisticated frameworks and fast engines so much that we’re slowly forgetting how computers work. Locating the slow code is easy, but what do you do next? Why exactly is it slow, and how do you make it fast? Time to regain the lost art of algorithmic performance optimization! Vladimir shows you how — on practical, real-world cases of optimizing popular open-source libraries, PR by PR.
