Elixir/Erlang's core strength lies in built-in distributed computing, with OTP offering robust primitives for fault-tolerance, node synchronization, and process communication out-of-the-box. While Go excels at concurrency and can achieve similar distributed capabilities but often can be complex

[@AntonPutra]

ok, i'll try to add more use cases in the future

[@AndreiBurchack]

Erlang/Elixir webserver library called cowboy should be tuned up (unfortunately or luckily). With basic settings it's like postgres with settings out of box. Also BEAM also should be tunned up. With tuning we've got not so big gap between this technologies in our tests (1-5% in peak). I'm not expert in Elixir but if you will compare Erlang, i can help with tuning/tests.

I agree this test is comparing apples to oranges and I say Elixir shines for the web and the BEAM is very much alone as a VM with their concept of processes. For the same amount of request a very fast web sevrer is less costly but Elixir will save you cost by other means such as having no need for external services for pubsub, caching, background task and to not have to write an API layer for Node to Node communication. On a side note, to solve some of the Elixir slowness it's easy to use Rust through Rustler. Scaling is still the hardest part of a system and Elixir makes it easier to have to rely less on the costly cloud.

[@AntonPutra]

ok thanks for the feedback

[@jsonkody]

First - I like the video, it was really interesting! 😊 For people who know nothing about Elixir: Elixir's strength lies elsewhere. Everybody knows that on a single PC, Elixir probably loses to Go in terms of raw computing power. However, the BEAM/Erlang platform is designed for massive, distributed systems that do not fail. Go is just a language-fast on one machine-but good luck implementing the features that Elixir already has baked into its platform. It's kind of an apples-to-oranges benchmark, but it's still interesting to see exact numbers on one machine. I understand that many people have no clue what Elixir/Erlang/BEAM VM is and think it's just another language-I was one of them not so long ago. Let’s just say that comparing the speed of Go and Elixir is like comparing whether an athlete can do more backflips than Gandalf. Sure, he probably can, but Gandalf has way more tricks up his sleeves-tricks no athlete can match.

[@jsonkody]

That said, if you need raw performance to save server costs, or you're sure a single server is all you'll ever need, Go is an excellent choice. But if you're building distributed systems or unsure about future scaling needs, Elixir and the BEAM platform are hard to beat. It's all about using the right tool for the job! 😊

[@gabrielg9592]

I am quite interested in Elixir, and also I saw one of Sasha Juric's talks once and I loved what I saw from BEAM/Erlang. But I wonder... the problems that BEAM and Erlang solve aren't really that common, are they? And it seems that if a company would have those problems, then it means that they probably have the means to pay for top-class software engineers that could solve those problems using languages like Go, correct? Or am I missing something? Granted that Erlang/Elixir would probably be easier (and that could mean it would be cheaper as well), but sometimes language adoption is important, and Go > Elixir in terms of adoption.

[@BlackistedGod]

a stup!d reasoning for fanboys when their favorite language got murdered by other language in performance. do you even understand the point of this benchmark? both are being use as goddamn webserver for handling HTTP request to determine their performance, nothing else. these are for those who want to consider efficient with minimal "resource usage" for building a web app and how a typical webapp will be deployed/setup. but your reasoning is not even related on the point tested here.

[@jsonkody]

​@gabrielg9592 Well, I’d actually say those problems are extremely common-and they’re often solved poorly. Companies tend to reinvent the wheel over and over, resulting in buggy software that takes years to develop properly. The BEAM platform provides a robust foundation to avoid many of these pitfalls right out of the box. That said, the one big challenge with Elixir/Erlang is its niche status. There aren’t many developers familiar with it, so it feels risky for companies to adopt it. The concern isn’t just about the lack of developers-it’s also about committing to a large, critical codebase in a language that few people know well. That can make companies hesitate, even if the technology itself is a great fit.

[@iddiiddrisu5971]

@@jsonkodyYes i agree. Erlang and BEAM have a lot of mechanisms in place for things like clustering and fault tolerance. But let's face it, in it cloud era, most people don't have these concerns as they are happy to ship that problem away to their infrastructure using their most powerful magic spell, "kubernetes". Distributed system choices are not really a headache on the language level but now become a whole host of tools and tricks.

9:00 is this always true, that creating a new connection for a request is expensive? I have a production EC2 instance in the same region as an RDS instance, connecting through a private VPS. When I measured the time to initialize a new MySQL conn in PHP, I was observing it being in the microseconds. Idon't remember the exact number, but this doesn't feel like an expensive operation, when we consider actually querying data

[@AntonPutra]

true, real-world queries with joins can be very slow compared to creating a new connection

[@LtdJorge]

The problem with connections in Postgres is that they are a forked process with its own memory for tasks. So if you quickly create and destroy connections, you create a lot of churn due to short-lived forking and allocations. i don't know about MySQL.

[@aresstavropoulos916]

I'm a little confused when you test the RPS metric. If you are reaching the computing limits and the RPS is started to cap out, what's happening on the client side? Is the request timing out, therefore concluding the server can't handle it? Do you instill rules on how long until a timeout?

[@aresstavropoulos916]

I think I understnad the correlation between availability and RPS. But why do we see such a huge drop in RPS in Golang, as soon as availability caps at 90%? Shouldn't we see the the RPS reach a constant line once Go's hit its limit, and see the availbility slowly go down from 100%, since your still increasing requests per second?

[@carloschavira8824]

Bro is cooked

[@AntonPutra]

i frequently set a timeout for 100ms, you can see it from the config. when the client times out, it gets a 408 status code, which decreases availability. availability = (successful req / total) * 100 config - github.com/antonputra/tutorials/blob/main/lessons/230/tests/1-test/0-config.yaml#L16

[@AmirHosseinHonardust]

I think considering the concurrency model of each, that makes some sense. When you do anything, especially, IO, in elixir, each request does not process it asynchronously to other processes. A bunch of stuff may have a single GenServer that processes its inbox synchronously. So if your server does one thing, a lot, and repeatedly, you get a result like this. In cases when the job of a server is more versatile, the concurrency model does a lot more for you and adds a lot of reliability with it. I have not tested this idea though. I'm just speculating.

[@AntonPutra]

ok thanks for the feedback, i may include more test cases in the future

[@AmirHosseinHonardust]

@AntonPutra no problem. I have done some tests right now myself. And I have observed the same exact drop because of the process number limit in Erlang. I have never increased it myself, but I bet increasing the maximum number of processes would have a huge effect on that sudden drop.

[@LtdJorge]

​@@AmirHosseinHonardustyes, BEAM should be tuned for the machine, but that is not as simple as getting an Elixir app running 😅

[@AmirHosseinHonardust]

@@LtdJorge well. I'm not sure why the limit on the processes is there as well. But to have one node responding to for example 20000 simultaneous users is also kind of weird when you can so easily distribute the workload with BEAM.

[@Voidstroyer]

This test doesn't show the strengths of Elixir. In terms of raw performance, Go is much better than Elixir. Although I do agree with you that these results are disappointing since it even loses out to nodejs. But Elixir shines in other areas such as making certain very hard problems trivial to solve (concurrency, distribution, fault tolerance, and self-healing). A better benchmark is Theo's video where he built the same app using 5 different frameworks (Go and Elixir Phoenix included) and Phoenix was the best out of all of them.
