JavaOne 2016: HotSpot Under the Hood

Have you ever wondered how the JVM works under the covers? How the JVM is able to JIT-optimize the bytecode classes and what the generated output looks like? This session shows how a compiled Java class is loaded in memory, when the JIT optimizations occur, and what the generated assembly looks like for hot code in the JVM. The presentation also looks at current object layouts, how the memory settings affect how objects are stored, and what effects this can have for high-performance Java code. Presented at JavaOne 2016.

More information about the presentation, including how to build hsdis, can be found at https://alblue.bandlem.com/2016/09/javaone-hotspot.html
