Polar Signals
Profiling Rust in Action workshop

About

Curious how to make your Rust applications faster and more efficient? In this 30-minute hands-on workshop, we’ll explore what continuous profiling is, why it matters, and how it goes beyond traditional profiling. Using real Rust examples, you’ll learn to capture On-CPU, Off-CPU, and heap memory profiles, tackle advanced scenarios like thread-level analysis, and even correlate profiles with distributed tracing data. Walk away with practical techniques to unlock deeper insights into your Rust applications’ performance.

This workshop runs on repeat in 30-minute sessions. Join anytime!
