Recent TechEmpower benchmark results have sparked intense debates in the software engineering community about language performance. In their JSON serialization benchmark tests, Go-fiber demonstrates exceptional performance by processing 225,871 requests per second, while Java Spring follows with 160,252 requests per second. In comparison, Python's FastAPI manages only 19,273 requests per second, and Ruby on Rails handles a mere 10,984 requests per second in the same JSON serialization test. These stark differences may lead engineering teams to prematurely consider language migrations in hopes of solving scaling challenges. However, real-world success stories paint a dramatically different picture of what truly matters for application scalability.
