Starting a Dedicated Web Performance Team the First Ten Months

on YouTube ↗26m

" summary

Pinterest launches a three‑person web performance team and within ten months builds a regression framework that catches commits before production, a deployable fleet that measures 90th percentile pin wait time, and a binary‑search tool called perf detective that pinpoints offending commits alongside the monitoring system perf watch. Work yields a 14–20% improvement on home feed PWT, ties metrics to engagement, and prevents regressions across 200 million MAU and ~1M requests/sec.
