In 2025, how do Node.js and Python compare in performance, scalability, and ideal use cases?

Evaluates event-driven concurrency, throughput, latency, and use-case suitability between Node.js and Python.

• Node.js excels in I/O-bound workloads like real-time APIs, chat apps, and streaming—handling up to ~90K requests/sec with ~31ms latency, thanks to its event-loop and clustering. • Python, though slower by default, thrives in AI/ML, data processing, and prototyping environments using frameworks like Django and FastAPI. Async frameworks and multiprocessing mitigate GIL limitations. Tags: nodejs, python, performance, scalability, real-time, backend
