I did a RIIR again and:
Two apps nearly-identical in functionality now. On startup, before processing anything:
#Rust + #Axum: 3.5MB RES
#Elixir + #Phoenix: 75MB RES
Literally 20x difference, and I haven't even benchmarked throughput/perf. For a use case where a big goal is extremely low resource use, this is huge.
(both of these are running in release/prod mode btw)
hahahahhahaa
first run is against the elixir app
second on against the rust version
lmao
It depends so much on what you are up to, I reckon. I've done a decent bit of embedded linux devices with Elixir now and the entire system can run happy around 150MB.
How was your Elixir experience overall? My assumption is that Elixir would let you work mostly at a higher abstraction level but I haven't spent enough time with Rust to know :)
I know the runtime properties are very different. Tokio seems have a lot of BEAM-like features but not the same type of runtime operating system features.
I don't really like Elixir-the-language very much, but I do think it's better than writing an Erlang again (I've done both professionally). I'm looking very closely at gleam and considering porting the bigger "sister" app to that, tbh.
Make sense sometimes, but eh. Not always.
