Perf Stories
summary
Case studies and concrete wins matter: code changes cut servers to one third while doubling throughput and halving latency, Pino logs 10,000 messages in ~250ms (100ms in extreme mode), 0x generates flame graphs from macOS/Linux stacks, autocannon saturates servers ~10% more than wrk/ab and scripts full CI benchmarks; discovered 25% gains by manual JSON building, 20–25% by using epoch ms instead of toISOString, and ~60% faster buffer writes after string flattening.
