In this video tutorial from New Relic, you'll see a full performance troubleshooting cycle from problem identification and diagnosis, to fixing the problem code, and then testing the optimized code and verifying the performance improvements. You will learn the fastest way to identify when your Ruby app is suffering from performance problems, how to narrow down your troubleshooting to the specific app component that is the source of the problem, and then seeing into that component to find exactly which code is causing your app to slow down and why.
