Presentation: "JVM performance optimizations at Twitter's scale"

Time: Wednesday 15:35 - 16:35

Location: Olympic

Abstract: Twitter is increasingly relying on services written in either Java or Scala and running on the JVM. While JVM gives us a world-class runtime in terms of operational stability, performance, and manageability, it is still not trivial to achieve the desired performance characteristics of the programs being run on it, especially when you're dealing with services that need lots of memory, or have very low latency requirements, or both. In this talk, we'll present examples of performance problems we encountered while operating JVM-based services and the ways we solved them.
