How fast can you process a billion rows? The 1BRC challenge went viral in January 2024. While the original solution delivered insane speed but likely resulted in hard-to-maintain code, this talk will guide you through initial tuning steps to achieve a 5x speed improvement. You'll learn about the JDK, the JVM, and your hardware, gaining insights you can apply to everyday challenges.

You'll also learn when not to do that!
