The High Performance Talk You Did Not Expect To Hear about Rust

Abstract

Rust makes things 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 can 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 build a multi-million TPS service.

Instrumentation at Scale: Having Your Performance Cake and Eating It Too

Wednesday Nov 19 / 11:45AM PST

In high-performance code, a single misplaced counter increment can cost more than the operation it’s measuring. That creates a paradox: instrument too much and you slow the system down; instrument too little and you miss the insights you need to continuously deliver.

Accelerating Performance by Incrementally Integrating Rust Into Existing Codebase

Wednesday Nov 19 / 02:45PM PST

In order to improve the performance of existing applications and services, we can identify the most performance-critical pieces and reimplement them in Rust as opposed to completely rewriting the applications from scratch.
