Ask HN: What back end can provide noticeable performance improvement over Rails?
Hi, pretty much the subj.
What backend framework / technology, if any would provide a noticeable performance in loading / response times over latest Rails?
Provided that:
1) Rails project is fairly optimized (Pagespeed 90+ etc.).
2) No particular requirements, such as an extreme concurrency (not trying to replicate Discord etc.) or extra-large downloads or video streaming / video chat / deep learning, just a very fast website with a database and a backend that serves it. A lot of the speed will be dependent on your ability to cache and your implementation of caching. After that, your speed will likely have more to do with your HTML/CSS/JS than your back end. But, generally speaking, a compiled, static language like C# with .NET Core will be faster than Rails. I don't have personal experience with them, but Rust, most JVM languages (e.g. Java, Scala, or Kotlin), and F# should also be faster. Again, a lot depends on your specific code.
