Alexey Shipilov, Oracle — Compress Me Completely JPoint Java Conference 2015 Moscow, April 20, 2015 Controlling memory usage is key to writing high-performance software. In this talk, we'll delve into the inner workings of the JVM and JDK, looking for ways the platform tries to save memory. We'll look at header and field packing, pointer compression, cross-generational heap reference accounting, autoboxing cache, and more. As a bonus, we'll peek at how the JDK developers are trying to silently compress user strings. We will generously season all of this with a description of possible pitfalls and performance measurements.
