September 22, 2020 | Virtual Meetup
On September 22, 2020, Java Champion Simon Ritter will present ‘Java at Speed: Building a Better JVM‘. This event is organized by iO Associates on behalf of the South West Java & JVM User Group, based in Bristol, United Kingdom.
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 behavior 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 want. We’ll then move on to discuss the three critical features of the Zing JVM that address these issues:
1. 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 optimized.
2. The Falcon JIT compiler that leverages the LLVM open source project to provide optimizations specific to the newest CPU architectures using features like AVX2.
3. ReadyNow!, which allows details of speculative optimizations and JIT profiling to be logged on production systems. ReadyNow! profiles can then be used to substantially reduce the warmup and de-optimization issues that affect performance when restarting an application.
There will be many opportunities to ask questions, plus we will open the floor for questions and queries you would like to discuss at the end.
