Eva Andreasson has a fairly entertaining and yet painful presentation around garbage collection that will probably will end with more questions than answers.
Jonathan Worthington explains how invokedynamic works, how he has been using it while porting the Rakudo Perl 6 compiler to the JVM, and its performance impact.
Hosted by Erik Meijer, who runs the Cloud Programmability Team at Microsoft, the panelists answer questions on C/C++ and Java performance, contrasting the virtues of native vs. managed code.
Gil Tene examines the core issues that have historically kept Java environments from performing well in low latency environments and how it can perform now without trade-offs and compromises.

Roman Gonzalez and Tavis Rudd discuss techniques for shortening the ClojureScript development cycle by using the same codebase for clj and cljs and automatically running tests on the JVM.
The panelists discuss the future of the JVM in the context of parallelism and high concurrency of tomorrow’s thousands of cores.
Charlie Hunt presents the fundamentals of JVM tuning and provides advice for developers on writing a Java application that performs well at runtime.
Howard Lewis Ship overviews Spock, a testing framework for the JVM.
Gil Tene discusses JVM observation-based runtime optimizations, ordering and memory model rules, basics GC functions, memory management, and JVM mechanics.
Sébastien Doeraene introduces Ozma – Scala extension providing declarative concurrency – with code samples, and explores what it takes to port it to JVM.
Emad Benjamin explains how to deploy and tune a JVM on a virtual infrastructure (vSphere), and how to tune the garbage collector in this environment.
