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

Compares throughput, latency, concurrency models, and ideal usage scenarios.

• Node.js excels in high-throughput real-time endpoints: ~90,000 requests/sec and ~31 ms latency using its event-based V8 engine. • Python, while slower due to the GIL, shines in data-heavy ML/analytics pipelines. Modern async frameworks like FastAPI, Uvicorn, or emerging JIT compilers (Python 3.13, Codon, Numba) help it compete strongly in backend workloads.
