In 2025, which backend platform—Node.js or Python—is more efficient for high-concurrency, real-time workloads?

Compares throughput, latency, concurrency model, and suitability for real-time or data-driven backend tasks.

• Node.js handles massive concurrency effectively: ~90,000 requests/sec and ~31 ms latency using event-driven I/O and V8 optimizations. • Python, while slower under GIL, remains strong in analytics, ML, and rapid prototyping using modern async frameworks like FastAPI/Uvicorn, occasionally matching Node.js throughput when optimized.
