Elixir is very good at handling many connections without breaking. So you don't need to give it any special attention for good performance. Here a benchmark with a lot of clients posting to the once-campfire repos. Elixir mops the floor with the Rust versions.
The problem with all of this that keeps getting glossed over is that Elixir is requiring all of this special attention to get it to the numbers it can achieve. I also believe those numbers under represent Elixir's potential but this isn't a "which is fastest" benchmark. It is "which is fastest without knowing how to write in that stack" benchmark.
"In an overload situation, the rust implementation delivers a whopping 1% of messages to all connected clients, and the Elixir implementation delivers 100% of messages to all clients, applying natural backpressure to writes."
I have a branch with various performance improvements to the Elixir version, focused on specifically the websocket side of things. I didn't spend much time on the rest.
The load generation code was flawed in overload scenarios because any socket that had an issue just stayed disconnected forever, so I assume no benchmarks were run in this fashion prior. Now those reconnect on disconnect and continue sending traffic (a more realistic scenario).
Most relevant finding:
In an overload situation, the rust implementation delivers a whopping 1% of messages to all connected clients, and the Elixir implementation delivers 100% of messages to all clients, applying natural backpressure to writes.
Speed is cool. Rust is fast. Speed is not even close to the most important thing when building real applications.

There were **18** performance pull requests to the Rust codebase to get the numbers originally reported, compared to one performance pass to both Elixir and Go versions. However, the Go version was ported from the optimized Rust version.
I took a stab at improving the performance of Elixir. I used the PR for Elixir that @ZachSDaniel1 posted and worked some more on it. In the benchmark Elixir is now faster than Rust (ccece30 newest commit) for the Sidebar and Search benchmark.
Last conversion of the Campfire from my token stash goes to JavaScript/Express. As with the others, I'm sure you can find more to optimize. But this gives you a sense of what order of magnitude these options exist within with agent-led development. github.com/basecamp/once-cam…
Here's a PR with the code: github.com/basecamp/once-cam…
I also tested it against an older rust commit (3fe9f61) - though not the oldest. It looks like there has been a lot of performance improvements made to the rust repo.
P.S. The screenshots I posted are missing "req/s".

This is like saying that, because we have calculators and spreadsheets, nobody needs to learn mathematics or economics.

Important stuff mentioned by @laut in his talk yesterday at @ElixirConfUY today: date and times are complex 🗓️
You just gotta suck it up and deal with that complexity 🛀
ALT Picture of a conference slide with the words: "Date and time have some inherent complexitites and limitations. Software languages or libraries can't always guess what you want."

“Make your life easier with the date and time types in Elixir” by @laut right now, the last talk before launch break #ElixirConfUY
I’m looking forward to speaking at @ElixirConfUY in Uruguay! #myelixirstatus
It’s time for @laut 🎉
With his “Make your life easier with the date and time types in Elixir”, he’ll cover when to use which date and time types, how these types work in #Elixir, and how they align with database types and Ecto.

Touch screens replacing buttons in cars makes for a terrible user experience and is dangerous too. A dangerous fad. Design is about how it works. Not how it looks.
