Presentation: "The War Against Latency"

Track: Java Now

Time: Tuesday 14:45 - 15:45

Location: Lille Sal

Abstract: It used to be that if we had a performance problem we looked at the code or used an execution profiler to find execution hotspots. Nowadays it is rare that an application is architected to run on a single piece of hardware. This and other changes in hardware have resulted in latency becoming one of the biggest impediments to performance. The change means that execution profiling is rarely helpful. In this talk we will explore sources of latency and what we can do to find them. We will also explore how virtualization can affect latency.

Workshop: "Java Performance"

Track: Tutorial

Time: Sunday 09:00 - 16:00

Location: Trifork

This seminar blends theory and practices with tooling that has been proven to be effective in solving real performance problems. The objective to demonstrate what steps are needed in order to quickly identify and eliminate performance bottlenecks. It will also help you to understand and avoid common and often costly mistakes that developers make when they embark on a tuning exercise. The tutorial will cover;


  • Elements and dynamics of a software system
  • The performance tuning environment
  • A simple peformance tuning process
  • Tooling
  • Java memory management
Bring your laptop as we will be working on a problem drawn from real world experiences. The hands on work is open ended and highlyinteractive allowing for the opportunity for us to learn from each other.
