    Question Performance on Android hardware including OUYA

    Recently I've come to suspect just how well Oxygene for Java's output byte-code performs on actual Android devices. My interests lay specifically with OUYA in my case, but has anyone done any tests or benchmarks to see how it would compare to say Eclipse or other Java language based compilers?

    I should have expected silence.

    Not many pascal developers own OUYA yet.

    Now if you want I belive I still have source code for several of my trivial applications which I used for testing various aspects and could actually serve as benchmarking tools like data sorting, multithreading thests, chached file copying (not using default OS file buffer), masively creating/destroying classes, overloading processor for testing system stability, file read rate test, and probably some more.

    *First of all Eclipse is "just" an IDE which uses the default compiler from JDK.* Not Correct!!!

    I haven't done any such tests yet, but I haven't been programming for a while as well. I'm planning on starting a new project with Oxygene which may be ported to the OUYA. There I might do a few tests to compare javac vs Oxygene.
    Otherwise you could do it yourself and share the results

    Imagine I've written something clever here inspiring you to make something awesome. If that happens give me credits

    I always think I sound like a complete jerk when I correct people but please understand it's for all that would read the topic, not anything specifically targeted at your good self


    Eclipse has it's own compiler that is seperate from javac.

    I should imagine that performance is much the same across the board. I'd expect the native javac and eclipse compilers to produce marginally faster code than Oxygene.

    As with FPC vs Delphi or GNU C++ vs Micrsoft C++, code structure is most important and choice of compiler when concerning performance is only a consideration if you're maxing out your target device. As you'd be aware of the most performance intensive games available for your target devices you can make a rough estimation of how 'busy' they are and design your own games to hover below those requirements to account for any slight performance penalty that may exist with Oxygene etc
    When the moon hits your eye like a big pizza pie - that's an extinction level impact event.

    Well turns out I'm the jerk I did not know that Eclipse sports its own compiler. Just assumed it would use javac.

    Our performance issues extend to any Android based platforms so even if you information is just about Android devices, it'll help. The only difference may be that OUYA is a quad-core.

    Well our game is not using object pooling, and we have to put it in, but I'm wondering if that may be a bigger problem than we think. The game does create and destroy objects, but not consistently. How much of a performance hit can your game take while you are not creating or destroying objects without the object pooling implemented?

    Are there other memory management issues such as Garbage Collection kicking in at other times for other reasons?
