Accelerate Next.js in Kubernetes

Watt, an open-source application server for Node.js, achieves 93% faster latency and 99.8% reliability for Next.js applications in Kubernetes by leveraging Linux's SO_REUSEPORT feature. Unlike PM2's cluster module (which adds ~30% IPC overhead) or single-CPU pod architectures (which suffer from isolated queue imbalances), Watt enables kernel-level load distribution across multiple workers within pods with zero coordination overhead. Production benchmarks on AWS EKS demonstrate median latency of 11.6ms versus 182ms for PM2 and 155ms for single-CPU pods, while maintaining near-perfect success rates under sustained 1,000 req/s load. The solution addresses fundamental scaling challenges in CPU-bound frameworks like Next.js that cannot implement early request rejection.
