The Art of Java Performance TuningSlides

Performance tuning Java is as much an art as it is a science. Understanding the intrinsic performance characteristics of method calls, heap allocations, and casts is essential for developing efficient code at the micro level. Understanding the overall performance of applications as a whole is essential for developing efficient algorithms at the macro level. It’s critically important in all cases to measure in several different ways and to double check that those measurements are consistent. It’s also critical to beware of the JIT effect: many things get faster with repeated use, even to the point where some things are simply free. In this presentation I will share my experience with performance tuning EMF and EMF-based applications specifically; the insights gained have broad application.
