Production profiling has moved from taboo to essential. Learn how to sample safely, minimize overhead, and turn profiles into a flight recorder for your systems.

Sampling profilers, overhead budgets, and differential flame graphs: how to observe live systems without becoming the incident you are trying to debug.
Learn how to identify the fast and slow paths in your code and keep the common case fast. This video uses flame graphs and histograms to show the divergence and offers three techniques to design for the hot path.
The Invisible Fork in Every Hot Path
0.750 USDCHot paths hide a silent fork between a cheap fast route and a costly fallback. Measuring how often that fork is taken, and how bad the slow side is, matters more than average latency.
Production profiling requires sampling, correlation, and strict overhead controls. Learn how to avoid common pitfalls and get actionable data without destabilizing your system.
Production profiling is a continuous telemetry problem, not a debugging session. The payoff comes from comparing a baseline against a canary and diffing the stacks.
