In practical perspectives, I'm mostly concerned about computer resources usage; I have computer resources constraints. So using Rust would benefit on that. But it is for a Web application backend. So, is it worth it having to learn Rust + Tokio + Axum, ... in this specific situation? Also, that this is mostly for initially prototyping an application. Also considering if I add developers in the future, they would most likely not be familiar with Rust, but with more popular frameworks such as Node.

The original was taken down in response to Reddit enshittifying, but it's still up on the wayback machine and the graphs were hosted on Imgur, where they're still up without needing the Wayback machine:
