TechEmpower's Round 23 benchmarks reveal ASP.NET Core on .NET 10 dramatically outperforms Node.js frameworks, with 23.4x better throughput in synthetic tests. Real-world JSON workloads still show a 3.0x advantage, while database queries favor .NET by 1.9x.

The performance gap translates to tangible infrastructure savings. Teams can handle more requests with fewer servers, reducing cloud costs significantly. Minimal APIs in .NET eliminate traditional boilerplate, offering Express.js-like simplicity with superior execution speed.

Organizations choosing Node.js purely for familiarity may be missing efficiency opportunities. While Node remains viable for many applications, .NET's edge becomes compelling at scale. Native AOT compilation in .NET 10 delivers 67% faster cold starts, crucial for containerized deployments.

Development teams should weigh these benchmarks against project requirements. The metrics are reproducible and publicly available, challenging assumptions about default framework choices for high-performance microservices.
