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.
I've had agents implement and optimize the Campfire web app in Elixir, Go, and Rust. Yes, Ruby is the slowest. I didn't care about that when the pay-off was huge in terms of productivity and developer joy. But if you're no longer reading the code? github.com/basecamp/once-cam…

The shown benchmarks use non-equivalent implementations: Elixir routes all DB queries through a single GenServer with Redis for jobs (retained from Rails), while Rust uses in-process queues, omits CSRF tags/fields, and applies other caching changes.

The easiest way to fall in love with your life is to work extremely hard for extremely long on something you find extremely important.

If someone is winning, they're not winning against you. They're winning against life.
So, drop the unnecessary envy and hate.

To receive such words from a Senior Counsel and a distinguished figure of Kenya's Second Liberation is humbling. Thank you Prof.

No one is perfect, but if you don't think highly of yourself, you'll ruin your life.

A billionaire literally explained how the entire economy works in 42 minutes better than most $200,000 MBA programs ever cloud.

Magadi road recently had some shoddy "expansion" job carried out on it by the irreparably corrupt KeNHA. But notice sth, the killer road is completely unmarked, pitch dark with not even a single streetlight in sight. Nothing good ever comes out of GoK, only destruction & death.
