{ "item_title" : "Performance Optimization", "item_author" : [" Zara Hurst "], "item_description" : "You've checked CPU. Optimized queries. Users still complain it's slow. What if you're looking in the wrong places? And what if finding the real bottleneck took minutes, not days?Every engineer knows this feeling. Dashboards look fine. Response times seem normal. Yet somewhere, something is quietly slowing everything down. You optimize one layer. Nothing. Another. Still nothing. Days disappear. Users get frustrated.I've been there. More times than I'd like to admit.This book won't just show you how to fix performance problems. It first teaches you how to find them. Fixing the wrong bottleneck is wasted effort. Fixing the right one changes everything.A Practical Guide to Finding and Fixing Performance Bottlenecks Across the Entire Stack walks you through a systematic method to trace slow requests, distinguish symptoms from causes, know which metrics matter, and identify bottlenecks hiding in compute, data, network, or code. Then it shows exactly how to fix them.I wrote this because I spent years optimizing busy-looking things while the real problem sat elsewhere. This is the book I wish someone had handed me.Why This Book Stands OutMost performance books focus on one layer or drown you in theory. This book covers the entire journey: finding what's broken, fixing it, and keeping it fixed.What You'll LearnTrace slow requests to their real sourceFive hidden bottleneck locations most engineers missWhy averages lie and which metrics actually helpRight-size compute instances based on real workloadsDatabase query optimization for real user waitsCaching that doesn't create new problemsNetwork latency mapping from user to responseWhen to optimize code vs. look elsewherePerformance testing that predicts productionCatch performance drift before users noticeTen real-world performance problems and exactly how they were fixedPlus practical tools: Bottleneck Discovery Checklist, Optimization Quick Reference, Design Review Questions, and Monitoring Setup Guide.Who This Is ForEngineers managing cloud systems. If you've ever spent days optimizing something that didn't help users, known something was wrong but couldn't find where, or wished for a practical guide covering the whole stack - this book is for you.Why You Need This BookPerformance work doesn't have to be guesswork or late-night incidents. There's a repeatable way to find what's slowing your systems and fix what matters.This book gives you that method. Written by someone who made the mistakes so you don't have to.Ready to stop chasing wrong metrics? Click Look Inside. Then add this book to your cart.Most performance books tell you how to fix things. This one first teaches you how to find them. Once you see the difference, you'll never approach performance the same way again.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/819/513/9798195138165_b.jpg", "price_data" : { "retail_price" : "13.99", "online_price" : "13.99", "our_price" : "13.99", "club_price" : "13.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
