I never able to understand language performance comparison using web frameworks. If framework does not give enough value why you would even use it and if it gives enough value, you test not a language but a framework’s overhead. Middlewares, pluggins, filters, validations, security, balancers, actors, thread, logging, and other stuff require certain orchestration that adds overhead even for hello world request. And if framework does not provide those, you better not using it just because it will not be able to scale up with your needs.
