Why Fast Matters
summary
Case studies show concrete wins: reducing latency by 0.3s yields £8.1M in extra revenue for a train ticket retailer, turning on gzip saves 43% of a large streaming service’s bandwidth, and cutting load time by 80% lifts organic traffic 80% and time on site 32%. Practical tools and tactics include Charles proxy for realistic 2G throttling, SpeedCurve/Dareboost/WebPageTest for continuous benchmarking, testing on a Moto G4 or Nexus 5, and auditing third parties where one tag once caused 98% runtime overhead.
