I’ve been out of the Java scene for a really long time, but will be coming back to it soon. I’m curious - these performance issues described here, are they inherit to how Java itself? Is it baggage from Spring/Boot? Are there ways to get more bang for the buck with some careful choices in a system like this?
The closest I’ve done to Java recently is C#, which I think may have similar challenges, but overall didn’t seem quite as bad if you avoided lots of framework extras. It also wasn’t something I was digging into deeply though, so perhaps I’m mistaken.
You can do AOT compilation with GraalVM to reduce both startup times and memory usage, but then you don't have the JIT.
It's a shame imo that it's not seen as a "cool" option for startups, because at this point, the productivity gap compared to other languages is small, if nonexistent.
