Explain Docker performance optimization techniques.

Docker performance optimization strategies: 1) Image optimization: Use Alpine Linux (smaller, faster), Multi-stage builds to separate build and runtime, 2) Resource limits: docker run --cpus="2" --memory="1g" myapp, I/O limits with --device-read-bps, 3) Storage optimization: Use overlay2 storage driver, Regular cleanup with docker system prune, 4) Network optimization: Use host networking for high throughput (docker run --network=host myapp), Custom networks for isolation, 5) Container startup optimization: Copy package.json first for better caching, Use exec form for CMD, 6) Monitoring: docker stats --no-stream, Profile with nicolaka/netshoot, 7) Production optimizations: Set resource limits and reservations, Configure ulimits and sysctls. Performance tips: Use read-only containers, Minimize layer count, Use .dockerignore effectively, Enable BuildKit, Use specific base image tags.
