Everyone should care about performance. It's not just about making your website or API or application fast, it's about doing more with less: cutting hosting costs by using smaller, cheaper instances, and reducing the environmental impact while you're at it.

In this talk, Mark will share how he took the One Billion Row Challenge from 2.2 minutes to 2.2 seconds using a variety of optimisation techniques. You will learn some simple patterns to improve the performance of your .NET code, and how to use BenchmarkDotNet to test your own algorithms.
