Answer
Minimize GC interruptions, offload CPU-heavy tasks to native modules, reduce promises, use real-time thread scheduling, pinned threads, predictable memory allocation, and remove unnecessary async layers.
Quick Answer
For ultra-low latency, the event loop polling mechanism (libuv epoll/kqueue) would need tuning — using busy-wait polling instead of sleep-based waiting, eliminating GC pauses via object pooling, pre-JIT-compiling hot code paths at startup, and pinning the Node.js process to a specific CPU core to avoid context-switching overhead.
