Track: Bare Knuckle Performance

Location: St James, 4th flr.

Day of week: Tuesday

Crushing latency and getting the most out of your hardware.

Track Host: Monica Beckwith

Java Champion, First Lego League Coach, passionate about JVM Performance @Microsoft

Java Champion Monica Beckwith is considered a subject matter expert, has several published articles and gets regular invitations to give talks on JVM/JIT Compilation/Garbage Collection (GC). She is also a JavaOne Rock Star.

Monica has made various performance contributions to the Java HotSpot VM by identifying the need for a NUMA-aware allocator and allocation patterns, reduction of redundant instructions, reduction of the Java object header, prefetching patterns, redundant array checks in a loop and various other optimizations for the JIT compiler, the generated code, the JVM heuristics and garbage collection and collectors.

Prior to joining Microsoft, Monica was the JVM Performance Architect at Arm. Her past also includes leading Oracle’s Garbage First Garbage Collector performance team.

Does Java Need Inline Types? What Project Valhalla Can Bring to Java

Inline(value) types are the key part of experimental project Valhalla which should bring new abilities to Java language. It's a story not only about performance, it's also a  story about safety, abstraction,expressiveness, maintainability, etc. But on this session we will talk about performance. Which performance benefits inline types bring to Java and how we could exploit it.

Sergey Kuksenko, Java Performance Engineer @Oracle

Understanding CPU Microarchitecture to Increase Performance

Microprocessors have evolved over decades to eke out performance from existing code. But the microarchitecture of the CPU leaks into the assumptions of a flat memory model, with the result that equivalent code can run significantly faster by working with, rather than fighting against, the microarchitecture of the CPU.  

In this talk, Alex Blewitt will present the microarchitecture of modern CPUs, showing how misaligned data can cause cache line false sharing, how branch prediction works and when it fails, how to read CPU specific performance monitoring counters and use that in conjunction with tools like perf and bpftrace to discover where bottlenecks in CPU heavy code live. We’ll use these facts to revisit performance advice on general code patterns and the things to look out for in executing systems. The talk will be language agnostic, although it will be based on the Linux/x86_64 architecture.
