Making things go fast in

" summary

Explains how to find real bottlenecks by measuring runtime with tools like Blackfire and by inspecting resource usage with a custom x-ray tool that shows filesystem calls, locks, cache hits and database queries with full stack traces. Demonstrates two GitHub apps that inject artificial delays per filesystem operation and per database query so slow remote setups are reproducible locally, arguing for frustration-driven development to expose issues hidden by fast SSDs and big RAM.
