Scaling Architecture
Practical guides on evaluating and communicating system performance — benchmarking methods, the right metrics for the right audience, and how to reason about optimizations at scale.
Quantifying Performance Gains: The Metrics That Actually Matter
A practical playbook for measuring any backend optimization — percentage improvement, speedup factor, throughput, percentile latency (p50/p95/p99), cost savings at scale, and how to present results to both engineers and stakeholders.
