// Run with: NODE_ENV=production LOG_LEVEL=warn node benchmark-server-uws.js
// Or override port/host: PORT=8080 HOST=0.0.0.0 node benchmark-server-uws.js
//
// CLUSTERING: When enabled with uWebSockets, uses SO_REUSEPORT on Linux for kernel-level
// connection distribution. Each worker binds to the same port, and the OS kernel distributes
// connections efficiently. Works great under real production load with many clients.
