SESSION + Live Q&A

Novel Algos and Optimizations in JCTools Concurrent Queues

Bitwise tricks, memory layout, minimal memory ordering primitives and some innovation result in queues that leave their JDK alternatives in the dust.
In this talk we will follow several examples of optimizations, tradeoffs and implementation details from the JCTools library. In addition we will explore the driving forces behind some of JCTools novel algorithms and their applicability.

Continuous Profiling in Production: What, Why and How

Everyone wants to understand what their application is really doing in production, but this information is normally invisible to JVM developers. Profilers tell you what code your application is running but few developers profile and mostly on their development environments. Thankfully...

Panel: Performance - What's Next?

A lot of the techniques and approaches that we use for developing and improving software performance are tried and tested rather than innovative. But what does the future hold - will be doing the same things in 5, 10 or 20 years time or will software evolve?
