Ben Evans Lightning Talk

New Relic recently published the results of their Java ecosystem research based on data sent to them by their customer's JVMs. Ben Evans, Java Champion and Principal Engineer at New Relic (as well as long-time LJC alumnus) joins us remotely from Barcelona for a lightning talk and Q&A about the results and what they tell us about Java usage in 2020.

Evolving Compilation with Graal

When Java was released in 1995 it was slow, a reputation it has carried for many years… Today Java can give performance that is comparable to C++ and can emit instructions that are more optimal than code which is statically compiled. But how?

This talk will explore practical examples and the subsystems that are involved in interpreting, compiling and executing a simple Hello World Application. We will dive into JIT compilation and the arrival of the JVM Compiler Interface (JVMCI) to explore how optimisations are applied to boost the performance of our application. We will discuss HotSpot, explore Graal and the JVM ecosystem to discover performance benefits of a platform 25 years in the making.
