Performance Testing for Modern Apps

on YouTube ↗44m

" summary

Shows concrete numbers and runnable tools: baseline tests using ApacheBench and Siege hit about 65 requests/sec at ~150ms, distributed tests with Bees with Machine Guns scale to ~306 rps at 163ms and up to 502 requests/sec with latency rising to ~360ms, scripted user-flows with Multi-Mechanize and Locust.io (the latter includes a web UI and distributed runners), client-side metrics via Google PageSpeed, WebPageTest and SiteSpeed.io, and failure drills like Chaos Monkey to see what actually breaks.
