## AI overview

This talk explains the design choices behind the JDK's garbage collectors and how Java memory management affects application performance. It also examines the relationship between RAM and CPU and questions whether Java's memory use is inherently wasteful.

## Source excerpt

In this talk, we'll explore why the JDK's garbage collectors work the way they do and how Java memory management affects application performance. We'll look at the sometimes non-obvious relationship between RAM and CPU, and why they must always be considered together.
