Go and C# represent different philosophies for backend development. Go offers superior memory efficiency (25MB vs 162MB), faster initial response times, and simpler deployment with 6MB container images. C# provides a mature ecosystem, comprehensive tooling, and better enterprise integration. Go excels in microservices and cloud-native applications, while C# dominates desktop applications and enterprise systems. Performance differences narrow under sustained load, with both languages suitable for production workloads. The choice depends on team expertise, infrastructure, and specific project requirements rather than absolute performance metrics.

I’m sorry, and I hope I’m not stepping on someone’s foot. But this article gives of a very AI LLM generated vibe. It full of statements that seems correct, but that ultimately is a matter of option or is simply plane wrong.

no charts, no graphs, no source code for the benchmarks, no hardware disclosure, not even an explanation of the methodologies behind the benchmarks…

Established companies often stick with the environments they started on, as it becomes to expensive and time consuming to change to drastically and might require the company to recruit new expertise. It is not as much as not wanting to change as being cost effective to stay.
Off cause sometime need forces you to that anyway

Having spent decades working with C# and the .Net frameworks, I realized that transitioning to Go was one of the toughest decisions I ever made. However, I couldn’t be happier with my choice! While benchmarks and opinions can provide some insights, they pale in comparison to the unique challenges you face in real-world scenarios. I strongly recommend experimenting with both languages in practical applications to find the right tool for your specific needs. In my experience, for most cases, choosing Golang was an easy decision.

It a “good” comparison between actual Go and past C#. Today you can do http without ASP .NET if you read the manual. Thanks Chat GPT for bad analysis.
