Id like to see a benchmark with the differences between microservices comunications : grpc, rest and rabbitmq -latency , memory and cpu using any linguage is fine

[@SkegAudio]

its amazing how the differentials are so minute the availability graph scales to show difference, but in great scheme of things they're all still within 99% available: thats crazy rust is so performant 😯

Based on your tests all of these frameworks performed really impressively. Honestly the differences seem to be rather small and I feel like using any of them would give you super high performance web server.

Great content, I was actually thinking of whether I use Axum or Actix in my project though my first choice is Actix. Now Im decided to stick with it.

[@StingSting844]

Please understand that raw req/s is not a metric to select a framework. Its a lot of different things. Top priority should be ergonomics and ease of implementation. The moment your app needs to handle 10k/s it's a huge scale already

well actix has more starts 😊

​@@theintjengineer I just did this test yesterday and yes Bun+Elysia is super performant. I did Bun vs Elysia and Bun got 47k rps while Elysia 60k rps in a 1 thread 10 connections setting. Any idea what's the optimization done by Elysia to achieve such performance?

[@Carlozei1337]

I see a video from Anton, I click and watch it. It's that easy ;-D

[@AntonPutra]

haha thanks!

[@shm236]

Correct me if im wrong, but actix utilizes a more singular request to thread strategy while axum uses a more work pool threading strategy. Considering they are

[@viniciusataidedealbuquerqu2837]

stateless tends to be more asynchronous no?

[@shm236]

@viniciusataidedealbuquerqu2837 stateless requests are more async/thread friendly but then someone needs to handle the state in the interim. I was attempting to reference the nature of how load is assigned to threads. The result is that axum FEELS nicer to build more complex middleware and such, while actix feels much more straightforward. But that's just my personal experience.

[@viniciusataidedealbuquerqu2837]

@@shm236 gotcha thank you

[@AntonPutra]

interesting

[@yelan5034]

Fantastic! It seem like there is not much performance difference between them. If I ever need to write a web application in Rust, I think I will go with the one that is easier to use and has better community support.

[@AntonPutra]

axum looks cleaner

[@adho12]

Do you have an idea what causes the degradation of performance? The usual suspects mem ans cpu seem to be good… Could you maybe have reached the host socket limits?

[@AntonPutra]

i don't think so, but i'll double check next time. It's a eks cluster and usually you don't directly manage nodes. i may try to using serverless eks (fargate) next time

[@agustinpizarro]

~25000 limit is very suspiciously associted to some hardcoded limit

[@sqrmap]

The combo of all services failing at the same time + no service being near their resource limits + no service p99 latency being near what would be required to cause a 408 response would indicate that some other limit had been reached before the services themselves degraded.

[@LKamii]

Was looking for this. This test is testing the aws nodes and not the frameworks. Great test setup otherwise and hope you upload a rerun after figuring out what limit you hit.

[@NekoApril]

This is actually a pretty good point, iirc the default limit in linux is somewhere in the 25k-32k range. And if they're all pushing the limits of the OS, that's insanely impressive for all of them.

[@AntonPutra]

thank you! i'll keep adding more metrics in the future just for the reference

[@hoarsebees]

26k seems pretty close to ephemeral port exhaustion. You may want to look into either increasing this limit or allowing the load generator to re-use connections between requests (Connection:keep-alive) or tweaking the load generator to not have more than that many connections open at a time.

[@AntonPutra]

[@specy_]

Here you are again

[@badscrew4023]

The fact the three start failing at the same moment, tells there is something common between the frameworks that doesn't tolerate the load, or perhaps the problem is outside.

[@AntonPutra]

yes, it's infra issue, more precisely the issue with a go client :)

[@mike-barber]

This _potentially_ looks like it might be hitting a different bottleneck. Maybe like the ingress controller or load balancer or something. I know from load testing my own Rust web application on K8s, the thing we max out first is the load balancers (haproxy in my case) rather than the app itself. Anyway, it looks very similar to what we're observing here - the app never gets close to 100%, but the load balancer pods are maxed out. A good way to rule this out is to run the app directly on an EC2 machine and hit it with wrk, or something equivalent that can generate enough load without hitting limits itself. Then we'll know how fast it actually is before plugging it into K8s. You might have checked this already, of course - but would be interesting to know :)

[@AntonPutra]

Thanks! I don't use a load balancer or ingress controllers in this video, only native Kubernetes networking (Service of type ClusterIP). yaml - github.com/antonputra/tutorials/tree/main/lessons/206/deploy/actix-app

[@CalifornianViking]

I had exactly the same reaction. All three frameworks are failing at about the same time while all the other metrics seem fine. Why would it stop serving if the latency is way below 1 mSec and the CPU (40% ish) and memory loads (1.5% ish) are fine? What else could be causing the failure

[@AntonPutra]

@@CalifornianViking it could be dns, cause i was using service name

[@CalifornianViking]

@AntonPutra I don't think it would resolve the domain name that often Did you check other constraints such as networking or container limitations? Could you run the test on bare metal or in a VM?

[@hoarsebees]

I agree with this. TechEmpower’s Actix gets over 1M RPS, so failing at 26k is a red flag.

[@BosonCollider]

A failure mode where latency goes up to 2 ms and "only" 99.8% availability is fun

[@AntonPutra]

well it was done on the same vm without any external dependencies so i think it is reasonable

[@shneor.e]

All equally slow lol

[@pietraderdetective8953]

For the slower (Python) frameworks, there are methods to make them more performant rather easily. 1. Use FastWSGI for Flask or other sync based frameworks. 2. Use Granian for Quart/FastAPI or other async based frameworks. Yeah they are slow, but to make them moderately fast is easy. Note they're never gonna reach the same levels as Go/Rust/Zig.

[@MrHirenP]

Very interesting charts. But what’s the takeaway? All three seem to perform similarly. Is it fair to say that the choice depends on developer experience? Or is there something else to consider at runtime?

[@AntonPutra]

So far, yes, it's about developer experience. I'll keep adding more metrics and graphs, and over time, I may discover additional behavioral differences.

[@DavidAlsh]

I couldn't find the source for "aputra/utils-tester-amd64" but if you exceed 128 concurrent connections the Rust servers will stop processing new connections by default. I'm not sure why the Rust stdlib has such a low default for max concurrent connections - but that might be why all of the servers all tanked at around the same req/s despite having plenty of CPU and RAM to work with. I raised a PR for your previous test increasing the max connection count

[@AntonPutra]

thanks! merged i'll try in new video

@@AntonPutra the big question for me is the inflection point where value switches from scaling lambdas to servers running fargate ECS and ec2 reserved instances. The numbers are of course heavily determined on what you want them to do, but it'd be nice to see rules of thumb, eg: 15kreq/sec for random crud updates is when ECS is more cost effective than lambda, so if you're under that stay serverless

Well, that's a typical deployment. I may go over each optimization technique I've got so far in the future.

Looks like you're using the multithreaded flavor runtime for Tokio, but for containers I would choose the single thread flavor, since you don't have CPU cores, and the workstealing overhead is quite substantial.

I'd argue it isn't overkill if it means you can reduce your hosting costs by a large margin. To get close to this in ruby/python you'd need many more instances running, load balancers, k8s (maybe). Where here you can run one instance and not need to bother with any of that complexity
