FastAPI vs ExpressJs please

[@vamshiaruru5494]

this is like coughing baby vs atomic bomb

Updated my checklist: 'Use non-blocking async libraries when possible.' 😊

[@DavidSmith-ef4eh]

Spoiler: Go wins.

Can we have a spring boot performance benchmark? I'm curious how it will perform in comparison with other tools/languages and with virtual threads and without it

[@AntonPutra]

yes sure

[@pable2]

@@AntonPutra Spring boot vs symfony + frankenPHP/swoole?

[@mogaclub]

spring boot vs quarkus

[@jorgetovar621]

It would be great to have a long video setting up all of this and learning how to perform these benchmarks. That way, we could better understand the process and contribute more effectively to this code. Really good job!

[@AlokSingh-rj1gt]

One of the fastest tortoise vs cheetah.

[@AntonPutra]

😊

[@SAsquirtle]

I understand not everyone knows every language/framework well enough to make a decent app but cmon you could've done some more research. 1. Why are you using a synchronous pg driver with an async endpoint? this blocks the event loop till each query finishes. If you absolutely want to use the sync driver, use plain def routes without async. 2. Why aren't you using asyncpg with async endpoints? the whole point of FastAPI is to make completely async REST APIs which use async packages. If you cannot find an async package or method, use run_in_threadpool with the sync method.

[@muray82]

This is why he ask for PR in repo.

[@SAsquirtle]

@muray82 then what's the point of the video? PRs are fine for minor improvements or enhancements but these are major issues which should've been addressed before the video was made

[@SAsquirtle]

Also want to clarify that even with the changes I mentioned, python and fastapi will still lose terribly but no where close to this extent

[@omlanke3466]

I was looking for this comment. He is not using an ORM in go, but he uses SQLModel in python. ORMs significantly slow down apps too. This comparison should be retested using FastAPI with plain asyncpg.

[@tuanvumaihuynh]

Using asyncpg with proper configuration can indeed improve FastAPI's performance significantly. There benchmark in repo show that it outperforms pgx.

[@pi3ni0]

Based on this and other videos, I didn't realize how efficient Go was! Thanks for sharing

[@mickhuby8786]

Just what I’ve been waiting for! Thanks for doing these benchmarks.

[@fluxcaruso345]

So the conclusion is use go for any backend service if you dont have any spesific requirements that force you to use another language

[@boburnomonov-d6s]

hell yeah

[@DavidSmith-ef4eh]

nah, dotnet. I rather sacrifice 20% of performance for all the nice things you get in dotnet, like pattern matching, extension methods, linq and of course the most advanced ORM in the world.

[@rodjenihm]

@@DavidSmith-ef4eh Is it even sacrifice in performance? Go might be even slower than C# and even Java nowadays.

[@tpadilha84]

I suggest you to use whatever technology makes you the happiest and most productive. These benchmarks are rarely representative of real world, most apps will never reach the level of concurrency tested here.

[@DavidSmith-ef4eh]

@@rodjenihm nah, he did a benchmark, dotnet vs go. although it's dotnet 8, and go won. I believe go would even beat dotnet 9, but not by much.

[@andreyvershkov4072]

Top video! Thanks. Please make OpenSwoole/Swoole (PHP) comparison vs Go.

[@ZuvielDrama]

The Switch from C# to Golang was a right one. Golang has the best simplicty / speed ratio. Using rust or c++ is more performant than golang. The costs are complexity in the codebase. Not to mention golang gives you one binary to deploy. This compared with c# dll hell...

[@DavidSmith-ef4eh]

which orm language do you use for go. Most of them require you to write SQL or generate helper code based on exisiting sql files.

[@allanamaral2587]

And that’s a good thing! After spending hours profiling and debugging slow LINQ queries you start appreciating writing just SQL

[@Bob-qz5yj]

C# has excellent aot support. You can often get one binary just like go if you prefer

[@DavidSmith-ef4eh]

@@allanamaral2587 just log the query lol, then fix your linq code

[@IncomingLegend]

try to compare Go with Gleam

[@AntonPutra]

ok

[@infantfrontender6131]

It will be the same result as with an Elixir because Gleam uses the BEAM and OTP

[@Gruak7]

@@infantfrontender6131 Could be but Gleam has its own ecosystem and a different web framework so there might be some differences.

[@KayandraJT]

@@infantfrontender6131 gleam is currently slower than elixir. the creator of gleam is focusing on improving performance so go slaps gleam atm

[@subbotin.monster]

Could you compare Django and FastAPI?

[@AntonPutra]

yes and flask

[@Imam.Mehdi_]

Also I was curious how much a certain hardware can handle load,,, can you benchmark different VPs or ec2

[@bartoszstasiak237]

As a Django developer I would love to see this

[@ridhotamma6331]

FINALLY!, what I've waiting for so long, thank you Anton!

[@AntonPutra]

my pleasure, i hope someone can improve it and i'll rerun it

[@obamna36]

Go is always a good pick for api server. good dev ux and decent performance. if you want top tier performance but with a longer time to write pick rust.

[@AntonPutra]

i love rust

[@roccociccone597]

I have tried rust for web development. Unless you need the utmost performance Go is going to get you 95% of the way.

[@KayandraJT]

tbh i used to be one of those people who thought like this... then earlier this year, i decided to give rust the love it needs and learned it... my productivity in go and rust is around the same also because i still use both of them. rust for me does not take longer time to write, i'm about as productive with both.

[@StingSting844]

This was brutal. Yes, the python version can be really fast too but the main point is that the speed in Go is something you get by default. If you're building for release speed then use python. If you are building for performance then use Go

[@neoko7220]

Waiting for php

[@freedomseekerism]

lmao

[@DavidSmith-ef4eh]

@@freedomseekerism you might be surprised that PHP (the swoole version) could be just 10% slower than go.

[@qwerty6713]

That's interesting that difference was only 7-10 times. But if we add business logic, than difference will be more significant

[@AntonPutra]

sounds about right

[@roccociccone597]

oh it is. As soon as you have any form of looping in your code python shits itself.

[@ramonpereira4460]

I see that your are using C instances! Thanks a lot, Anton. Maybe try C instances vs M instances! Also, at my previous job, we had 1000 instances of FastAPI for ML inference and 1 Golang instance distributing to all of them. Golang is very fast.

[@SnazzieTV]

Python and speed can never go in the same paragraph.

[@DavidSmith-ef4eh]

maybe you could get python like syntax in the fastest language that even beats rust. But don't follow that project right now. It's called mojo, if you want to look it up.

ok i'll take a look

it runs the same as Django because of sync nature of your app. IO is getting bottlenecked. waiting for a true async version

When Python surpasses Go, it will truly become the best programming language ever! )

[@roccociccone597]

so never then? Python can't even match JS and JS sucks balls for performance.

[@AntonPutra]

i'll be waiting

[@BlackistedGod]

Its better to do this comparison with another interpreted language like PHP (Laravel, Symfony) or JS frameworks (Express, Next). Python is the slowest language and we would already know the result if its being compared to any compiled languages.

[@AntonPutra]

true, but fastapi uses a lot of new features, including coroutines and type hints, and on the official website, they compare fastapi with go and nodejs

[@iddiiddrisu5971]

Golang is definitely winning here!!! 😂 FastAPI vs Spring might be more fair. I can't think of any golang lib that would be as slow a FastAPI in terms of latency. Let me watch now and see.

[@pickle1987]

[@trsdesrn5246]

Just a newbie question: if Python is so slow compared to Go in almost all the frameworks, what is the advantage to adopt Python over Go for such applications like backend development?

[@DavidSmith-ef4eh]

well, go lacks language features and is very verbose. which means you have to type a lot, but the code is easy to understand. personally not a fan of typing a lot. But even then, I'd still use go over python on gunpoint.

[@rida_brahim]

at this point it's pretty obvious that python backend isn't the go to tbh, I don't care if you got 10 users or 100m users you just avoid python. the amount of time and energy you would spend on python can be spent on elevating your skills on a better language ( talking web development only).

Why are you refreshing model after insert? it is useless and only make additional requests. I am also not sure sqlmodel is a good thing to use. Try mapping sqlalchemy to dataclasses directly.
