Python and Ruby are probably the slowest commonly used languages, they are on the order of 10x slower than comparable C code. Comparatively Java/JS/.NET sits around 1-2x C speed, with .NET exposing some lower level details allowing manually fine tuning the performance, while Java has hands down the best GC implementations out of these 3. So one can’t objectively order them, for CRUD apps all 5 are great, and I think that there are very very few areas where C#/Java is not a good choice for performance reasons and you have to go lower level to C/C++/Rust.
