I'm using Rocket for a small production application for my PhD project. One supervisor recently took over the project and asked me where he could connect a log stream to detect crashes. I said: "I don't know. I never have crashes". At the same time, maximum memory consumption is about 15 MB (3% of 512 MB) and CPU load 0.1% on a Starter instance on Render. So credits to the Rocket maintainers for making Rocket such a reliable piece of software!

These numbers are fine and all, but what really matters is how many requests per second it can do. Combined with response time across a timeline where you gradually increase the number of clients (fake or real). To observe where your server experiences pain, and watching how it deals with it, and how/if it recovers is super useful. Benchmarking tools to pound your servers are plentyful, and these stats (connection/sec and avg response time) combined with the hardware spec is what makes a good praise or diss of a webserver performance. Maybe you'll never intent do draw a huge load for real. I'm just saying its performance can be measured better than its cpu and ram usage while on low or no load. Even if that is a useful aspect in some sense. Unless this is serverless of course. New ballgame entirely.

do you think it would be hard to transition to Rust and use Rocket? I mostly just python and kotlin as my languages

  In my experience, the more programming languages and frameworks you know, the easier it is to learn a new one. So it depends on how much you know already and how much you want to learn.

  Learning Rust can be challenging, especially if you're accustomed to Python or Kotlin. The Rust compiler is strict, which can be demanding for programmers. However, the effort can be rewarding due to Rust's advantages. Expect a slower pace of progress, as tasks that are straightforward in Python or Kotlin may require more time in Rust. The difficulty level is higher, but with motivation, it's certainly achievable.
