r/golang on Reddit: .NET says golang 6x times slower than .net and slower than nodejs

October 4, 2025 -

I'm not a fan of any language but I know that there are some advantages and disadvantages of languages and framework alongside platforms matter - PHP is slow, yes it is slow comparing to any other languages but if you setup frakenPHP or swoole then is may compare with other languages -

I was just visiting dotnet page and saw that there is benchmark says 6x times faster than go and go even slower than nodejs

Why is it like this ? I'm not saying this is wrong and they are lying but, what is the explanation of this ? What does matter most such test cases?

Slower than node? Then why are they rewriting the typescript compiler into Go? Slower than .net? That's going to depend on your use- case but Microsoft has been converting library methods to SIMD, so there is some likelihood that some things are faster in .net.

October 20, 2024 - My experience with Go/C# for backends in the real world, is that Go typically delivers significantly better throughput, latency and startup times while using substantially less resources, with no specific effort put into optimization (assuming no glaring mistakes that tank perf).

.net core vs go

Even if .net core is in RC we can continue to develop with the classic .net and switch to core gradually. We are in a phase of "changing" and we are starting to do web apps with angular etc, my boss is also considering nodejs because we can use a single language both server and client side (web) My will to choose golang maybe it's selfish but i think that in long term Go is a better choice performance wise, license costs (maybe by adopting go we will be more willing to use linux and open software) but also because switching to something new (and better for my point of view) can be an opportunity to loose bad habits in development

r/dotnet on Reddit: Should I stick with ASP.NET or switch to Go (Golang) for backend development?

June 15, 2024 -

Hi everyone,

I'd appreciate your input. I'm a programmer with about a year of experience in ASP.NET, primarily because it's what my current company uses. However, I'm really interested in Go (Golang) and am considering whether to shift my focus.

Currently, my role isn't fully focused on coding, but more on analysis. While I've delved into ASP.NET over the past year, Go seems to offer better performance for backend development. This has me torn between continuing to master ASP.NET or switching to Go.

I understand that many enterprises use ASP.NET, but I'm also aware of a trend towards Go for its performance, especially in startups and modern companies. I could be wrong, though, so I'd love to hear your thoughts and suggestions on which path might be more beneficial for my future as a developer.

Thanks!

Focus on .NET because you are working for company. If you prefer Go, find other job that use Golang. But you have to be very good developer. No one want to hire newbie unless they are willing to give training.

If you're doing "analysis" but just buy marketing at face value about go having "better performance" without numbers, sorry but your analysis is just bad. Startups use tech frequently because it's "cool", not because it's technically the best decision. There are reasons to pick Go over dotnet, but you didn't find any.

ASP.NET Core 8 achieves unmatched throughput due to its optimized threading model, high-performance Kestrel server, and task-based asynchronous handling.

r/dotnet on Reddit: .NET vs Go vs Node

October 4, 2022 -

Hey guys, I’m trying to decide and convince my superiors that .net is just as performant as Go or Node but I need some help.

SOME CONTEXT AROUND THE PROBLEM: We are trying to decide on a stack on GCP for a set of micro services. I am all for .net and postgresql / alloydb. We are planning to deploy the code on containers using Cloud Run.

The issue here is that my superiors think that .net is not as performant as go or node. IMO and all the research that I’ve done suggest that .net 6 is light years ahead of the previous versions and is completely capable of holding up against go or node.

My concern is also around the fact that code organization is so much better with c# compared to go or node. Simple things like IoC is better in c# vs go or node.

Any help on this is appreciated.

Talking about performance alone NodeJs is not even on the same ballpark as Go and .NET which are much faster in all conditions (gRPC, web throughput, memory usage, container size). Then for Go it will depend a lot on the web framework you choose, like Fiber, Gin, ... Check the TechEmpower benchmarks to get a feel of the discrepancy. Finally, even with the fastest Go web framework, .NET is still faster when using a high level stack (middleware, minimal APIs, ...). And. NET 7.0 is again faster than the current results which are on 6.0. Then probably these two will outperform your needs and will both be sufficient for what you want to do. The database layer might be your bottleneck, which would make the choice of web frameworka moot point. The tooling or confidence with the platform could be the second best differentiator. If you just want perf, then check Rust frameworks which are even faster right now. Disclaimer: I work on the perf infrastructure for the ASP.NET team.

June 15, 2023 - ASP.NET Core’s support for containerization technologies like Docker and Kubernetes provides a straightforward path to deploy and scale applications across multiple servers or cloud services. Golang shines when it comes to building high-performing, scalable applications due to its efficient handling of concurrency with goroutines and its lightweight compiled binaries.

does go add Generics till now ?

Top answer

It really depends on the benchmark used. Techempower shows .NET to be better performing for simple scenarios. In my stress tests Go and .NET are roughly the same with Go using less resources. I definitely prefer Go's faster startup time for serverless functions. Generics are slated for the next release early next year. The Go team is purposely holding back on enriching the standard packages with generics. It will be a few releases more before we see how generics play into http handlers.

I've done both and I find go to yield more performant code at the cost of harder to hire for developer positions. I also find it yields easier to understand code. Composition over inheritance is amazing.
