Production websites will serve as your example and guide to each andĮvery one of the strategies in this guide. Strategies on production websites like, , the official While preparing this course, I’ve implemented each of my performance These strategies have been tested and proven on my clients' sites and others. Used more than 20 different SaaS providers, performance-oriented Rubygems, backend service providers and more and found the perfect technical stack to make the entire performance optimization process simple (even if you’re a new developer or someone with a deep technical background).These strategies have solved 80% of performance problems in most applications.

Performance optimization on a full-stack web application is like looking for a black cat in a coal cellar - any one of a thousand things could be the bottleneck for your application. Server Do you know how your memory allocator may be affecting your performance?

This result has been experimentally verified at dozens of companies large and small. Others were the passion projects of developers looking to start a side business. Many were for well-funded startups, from Ivy-League incubators like YCombinator or 500Startups. Over the past 10 years, I've seen dozens of different Rails codebases. I also maintain Puma - my code is probably already running on your servers, today.
