NodeJS Scalibility Tips

" summary

Shows a concrete workflow: benchmark a simple QR PNG server with autocannon (200 concurrency yields ~100 req/s, avg latency ~2s) then compare to a minimal hello world (≈53k req/s) to find headroom. Use clinic.js (doctor, flame, bubble) to locate hotspots (png rendering function ~27% of time). Scale by cluster module or worker threads/piscina for a 3–4× throughput gain on an 8‑core machine, or by functional decomposition (microservices) and partitioning (sharding). Emphasizes logs metrics traces and choosing one primary optimization goal.
