MálagaJUG - Simon Ritter on Tour - Java at Speed – Improving Application Performance
Monday 7 May 2018, 18:30 - 19:30
Calle Severo Ochoa 21, Malaga, España
SESIÓN MUY ESPECIAL - Contaremos con la visita y presentación de Simon Ritter, deputy CTO en Azul Systems, Java Champion, Java Rock Star y experto mundial en Java, JVM, IoT y rendimiento de aplicaciones. Simon estará estos día en un tour por los JUGs de toda España cortesía de Azul Systems. Nos hablará sobre técnicas y buenas prácticas de la JVM para sacarle el máximo partido en escenarios complejos y con mínimos tiempos de respuesta. --- Java At Speed: How Azul Improves the JVM to Run Applications Faster (60 Minutes) Getting the best performance out of your Java applications can often be a challenge due to the managed environment nature of the JVM and the non-deterministic behaviour that this introduces. This session will start by looking at what we mean by speed and how the JVM, whilst extremely powerful, means we don’t always get the performance characteristics we need. We’ll then move on to discuss the three key areas that Azul have worked on to improve the JVM: 1. The newly introduced Falcon JIT compiler that leverages the LLVM open source project to provide optimisations specific to the newest CPU architectures using features like AVX2. 2. ReadyNow!, which allows details of speculative optimisations and JIT profiling to be logged on production systems. ReadyNow! profiles can be used to substantially reduce the warm up and deoptimisation issues that affect performance when restarting an application. 3. The C4 garbage collector, which eliminates GC pauses that affect the performance of an application even after all hot code paths have been compiled and optimised. With Azul’s JVM, your Java application can start fast, go fast and stay fast!
