.net 5 (and former .net core) was pretty fast. The issue was in serverless there is a pretty long cold start since the interpreter is still invoked which is like a mini virtual machine. If you're sticking to azure, they have a highly customized environment for it that I'm pretty sure saves interpreted output vs source code.

I would highly recommend golang to old school C# devs who are very comfortable with threading, thread safety, and mix of high and low level code in the same codebase.

edit: Best go devs I know are seasoned C or C# backgrounds.

Ok, here is another one, then.

You should learn to write some Go code then.

Why? C# fits the bill for everything I want to do. It's fast enough, it has great IDEs, it runs almost everywhere and there are more UI frameworks than there are JS frameworks /jk ;).

I have almost 15 years experience in it, why would I slow down my next projects by using a language I'm not familiar with (as long as C# fits the bill ofc). Learning a new language isn't a hobby for me, it has to be useful to me (I learned Flutter because MS Ui frameworks aren't a panacea).

Maybe I'm not following the thread (I'm not sure what "In what concerns .NET is wasn't really better" means), but what's the issue here? C#'s fastest framework beats Go's fastest by a marginal amount (60.1% vs 59.1%). That's probably within the error margin. Anyway, drawing sweeping performance conclusions from microbenchmarks is perilous--a high ceiling for an HTTP framework doesn't indicate anything about real-world performance for web applications (which are almost never bottlenecked on the HTTP framework).

The issue here is how many in the Go community like to boost themselves about how fast Go is, only because it is the very first AOT compiled language that they ever used, usually come form scripting language backgrounds and are influenced by the traditional Java/.NET hate, without ever using them in anger, including their AOT tooling.

So then we come these kind of assertions like Go compiles faster than any other AOT language, it doesn't have a runtime, its performance beats Java/.NET and so on.

I’m sure if you searched hard you could find a few people in the Go community who say silly things like that, but (1) you could find these kinds of people in any community and (2) in the Go community these people are quickly corrected and (3) no one in this thread is making these sorts of arguments (as far as I can tell) so your comment seems wildly off-topic.

Note the difference between “Go is better for certain cloud applications than Python, NodeJS, etc” and “Go is better than all other languages, full stop”.
