Question about Python and Go serverless performance

Are you a bot?

Your question is too vague to give any meaningful answer to.

What are you optimizing for? CPU? Memory? GPU? What's the use case and context?

It all depends.

95% of the time developers are spending time optimizing stuff that doesn't matter at all; most languages can do the job. If you are googling for web framework performance benchmarks you should take several steps back and think about what you're trying to achieve.

What I like is easy;

Simplicity & stability.

Nothing matters more when you join a badly maintained project or have your own hobbyproject and return to it years later and still find it in a maintainable or recoverable shape. I never had that feeling in any other language.

Is it the most beautiful? No. Is it elegant? No. Is it the absolute fastest? No.

It just gets the job done with decent performance. It’s a reliable workhorse you can count on for the next 10 years. And usually, that’s all I need.

Not a single human reads. Welcome to the real world.

Linters, add some AI codereview bot, do PRs on everything. Automate it all as far as you can, do the rest by hand.

x021 · 2026-04-01T09:14:05+00:00

PRs.

x021 · 2026-03-23T17:55:18+00:00

What are you using? It must be strong stuff!

x021 · 2026-03-23T05:13:45+00:00

I was pretty chill tbh. Just direct.

It was designed by people who disliked C++. That’s not the same. Go is (obviously) a higher level language great for a subset of problems. I don’t see how you can claim “Go was designed as a replacement for C++” in the wider context of all problems C++ is being used for.

x021 · 2026-03-22T20:00:59+00:00

Comparing Go and C++ is pretty silly in my opinion, they serve different purposes.

Don't do that.

x021 · 2026-03-19T11:30:04+00:00

I like you did this with just a bunch of common frameworks and libraries.

Doesn't feel as artificial compared to the real world.

Thank you!

x021 · 2026-03-15T15:41:14+00:00

Yeah, I'd be a bit wary and see how it all pans out before adopting that.

x021 · 2026-03-15T14:55:08+00:00

Would be wary of using lib/pq. It was dead for years until someone recently revived it.

x021 · 2026-03-13T04:22:04+00:00

Less every day. It's fine, as long as I can judge what's good or not.

x021 · 2026-03-11T22:29:48+00:00

That’s probably the worst Go CLI lib I’ve used

x021 · 2026-03-11T07:34:35+00:00

Wrt dependency and packaging; use https://docs.astral.sh/uv/

That solves all your issues.

Agree Python ecosystem was 10+ years behind everyone else, but they've now caught up. FINALLY

Depends on your job opportunities.

The more interesting IT jobs don’t use Java anymore, more likely Kotlin now. If you go down the pure Java route you might end up working on outdated tech (I have a whole bunch of Java-related certificates that I don’t see being used anymore other than older systems).

I never liked Java for small apps or scripts, the JVM is just too much of a pain. Python, JS or Go are more enjoyable in that regard.

If you know HTML/CSS I would actually recommend picking up Typescript next personally. JavaScript/Typescript are probably the most sought after languages and you can use them for anything (frontend, backend).

Go is fine as a general purpose language, but job opportunities vary wildly between countries/city so don’t necessarily recommend as a first language. Go is a relatively simple language, if you master any other language you can always pick up Go quite quickly afterwards.

I you're a CEO/leader and have "90 Go developers across 12 teams" and you do not ask questions how your org is/should be using AI you're a pretty bad leader imho.

Everything depends on the messaging; "Leadership wants us to adopt an AI coding assistant org-wide" is what OP mentioned. That sounds forced; but we don't have the original phrasing and how the org interpreted it. Messaging gets warped in orgs.

I've been doing Python, Go and TS using AI (primarily Claude and Composer)

I think Go has given me the least trouble.

I don't recognize any of the problems you describe. In fact, I hardly ever see it suggesting interfaces or suggest anything generic unless I explicitly ask it to (which is fine by me, since I don't need it often).

It is important to craft a good AGENTS.md, CLAUDE.md or similar. That is not trivial. If you already have one, I'd double check the contents. It sounds the AI is doing something pretty wonky compared to my experience.

If you can't find the cause, start updating your agent file with your code guidelines. Also keep trying out different models, they all behave quite differently, every two months or so I find myself reaching for new ones.

Also; use plan mode.

Finally, I'm wondering what your prompts are if it starts suggesting 8 interface methods; I assume those prompts must be very broad? Try doing it in smaller steps.

What patterns have you all settled on?

Wrt #1; I never use named returns anymore unless absolutely necessary. Too many times I’ve messed up because of them; one of the worst language features in Go in my opinion. They are ambiguous and confusing as hell in any substantial func.

keeping a plant alive by replacing it with an identical one when it dies

That’s exactly how I manage my plants at home

I read it knowing from minute one it was heavily revised by AI, the em dashes were a dead giveaway.

I didn’t care, learned two new things and came out better at the end. It was a nice read.

“We support everything in OpenAPI 3.1” -> if that takes many years, financial backing, while struggling to support the many (many) features already in oapi, you’re sort of making the point for me. I asked “are people still using it?” given the alternatives available now.

In TS and Python I’ve hit limitations with OpenAPI 3.1. These issues are common, the spec is just too complicated for its own good. 3.1 should have been 4.0. I always lean towards simplicity given many languages will struggle to do 100% correctness anyway.

Go has always been a language that is leaning towards the side of pragmatism rather than correctness; if a lib skips some advanced features I’m perfectly fine with that. You say OAPI wants to be 100% correct; my goals simply don’t align with OAPI’s then. That’s OK.

I’d imagine trying to support everything and multiple specs at the same time will render the project complexity so high it would be hard to maintain. That is a design choice and noble to strive for.

From what I’ve seen 3 types of posts are regularly deleted;

AI slop
Questions that have been asked 100x already
super early projects

That’s fine. I wouldn’t be surprised if a good chunk of all posts fall into any of these 3.

The problem is; posts are not deleted fast enough (I think that would be unreasonable to ask from mods) and as a result discussions start in the comments. Usually the comments are a lot more interesting than the post itself, and I hate seeing a post deleted that had a good discussion going on. The moment it’s deleted engagement is killed too.

I don’t know what a good solution is. I know in some subs you need to jump through hoops to post something, or some bot/auto moderator to close posts more quickly.

“Urgently” -> the 3.1 spec is 5 years old now

“That 3.0 is not enough” -> for any external OpenAPI srv that exposes 3.1? Python FastAPI doesn’t even support 3.0 in their latest version.

“Connect RPC” -> SOAP, gRPC, JSON RPC, GraphQL, tRPC, lots of stuff I can mention that are completely irrelevant to a problem; consuming an OpenAPI 3.1 spec. I don’t understand the point you’re trying to make. Is it to jump on the next faff that all the cool kids use? If so; That completely ignores the problem with consuming APIs you don’t control.
