Java Performance: Beyond Simple Request Latencies

When someone says “Java performance,” most Java devs hear “request latency” and a large part of them say “I’m already meeting my SLAs” or “my app isn’t latency-sensitive.” But Java performance has many more dimensions than that, and they matter for all kinds of Java apps—from ultra-low-latency FX trading platforms to long-running data ingestion jobs running at 2 AM on a Saturday.

In this session, we’ll go beyond the basics to look at the full Java performance picture: median latencies, latency outliers, freezes, pauses, server max carrying capacity, how your app behaves when it first starts up, carbon footprint, and more. We’ll check out the full landscape of tools at your disposal, from the newest JEPs in OpenJDK to GraalVM and Azul Platform Prime, and develop strategies to optimize whatever matters most to your team.
