Den Odell

Performance Engineering in Practice is now available in MEAP, giving you early access to Den Odell’s approach to building systems that stay fast as they evolve.

The book introduces the Fast by Default model, which treats performance as a design concern rather than a rescue mission. Instead of waiting for production pain, you learn how to shape decisions early so performance issues don’t accumulate in the first place.

A central idea in the book is the System Paths framework — a diagnostic language for understanding where time, resources, and contention actually flow through your system. The techniques aren’t tied to a specific language or stack, which makes them useful whether you’re working on web apps, internal tools, services, or distributed systems.

The examples focus on situations many teams recognize:

• An internal dashboard that becomes painfully slow
• Cascading failures triggered by a struggling API
• Performance regressions creeping in through normal development

Along the way, the book digs into practices that make performance work sustainable at the team level: profiling habits, shared dashboards, CI performance budgets, and design reviews that keep discussions grounded in user impact rather than guesswork.

MEAP readers can start exploring the material while the book is still being written and help shape its final form through feedback.
