Hi everyone,

I have some news I've been sitting on for a while. My new book, Performance Engineering in Practice, is now available through Manning's Early Access Program.

This is my third book and by far the most ambitious. It's the result of 25 years of watching teams fall into the same trap: performance problems surface after users complain, everyone scrambles to patch things, and weeks later something else regresses. I call this the Performance Decay Cycle, and I wrote this book to help teams break out of it.

The book introduces a framework I call Fast by Default: a way of embedding performance into how you design, build, and maintain software so that speed becomes the natural outcome, not a rescue mission after the fact. If you've been reading this newsletter, a lot of the thinking will feel familiar, but the book goes much deeper and lays it all out as a practical system you can apply to your own work.

The first five chapters are available now, covering the business cost of slow performance, user-centered goals, critical paths, and building speed into your architecture from the start. Performance principles don't belong to any single platform, so the book covers web, backend, mobile, and desktop with examples drawn from each.

Manning is running a 50% launch discount right now, and as a MEAP reader you'll get each new chapter as it's published, plus the full book on completion. There's also a discussion forum where your feedback will directly shape the final version.
