      In theory Java is very similar to C#, an IL based JIT runtime with a GC, of course. So where is the difference coming from between the two? How is it better than pascal, a complied language? These are the questions I’m wondering about.

      And it powers a lot of phones. People generally don’t like it when their phone needs to charge all the freaking time.

        I ran Linux with KDE on my phone for a while and it for sure needed EVEN MORE charging all the time even though most of the system is C, with a sprinkle of C++ and QT.

        But that is probably due to other inefficiencies and lack of optimization (which is fine, make it work first, optimize later)

          Yeah, and Android has had some 16 years of “optimize later”. I have some very very limited experience with writing mobile apps and while I found it to be a PITA, there is clearly a lot of thought given to how to not eat all the battery and die in the ecosystem there. I would expect that kind of work to also be done at the JVM level.

          If Windows Mobile had succeeded, C# likely would’ve been lower as well, just because there’d be more incentive to make a battery charge last longer.

        I’m using the fattest of java (Kotlin) on the fattest of frameworks (Spring boot) and it is still decently fast on a 5 year old raspberry pi. I can hit precise 50 μs timings with it.

        Imagine doing it in fat python (as opposed to micropython) like all the hip kids.
