The Rust High Performance Talk You Did Not Expect

Rust runs faster, but it slows down engineers, right? This was our team’s assumption when we decided to rewrite our code from Kotlin into Rust. But we were wrong in completely unexpected ways. We learned that we could write very slow code in Rust, and we could also write features faster in Rust as a team. This talks dives into the unexpected aspects of Rust that we confronted as we built a multi-million TPS service.

We'll talk about features of the Rust compiler that help teams to move faster by bringing confidence to complex code. We'll also talk about what to do when your Rust code isn't as fast as you expect it to be, diving into tooling like benchmarking and flamegraphs.

This talk is aimed at engineers who are brand new to Rust or teams considering it. If you're a Rust expert, this probably isn't the talk for you (unless you're trying to figure out how to convince your team to use Rust).
