Priming Java for Speed at Market Open

Gil Tene, CTO and Co-founder, Azul Systems provides an overview of JIT compiler optimization techniques and their impact on common market-open slowdown scenarios. Gil also covers the technical issues behind such slowdowns, and discusses new techniques that may be used to avoid them, including the use of features specifically built to tame the JVM and improve behavior at market open.


QCon New York 2014: Priming Java for Speed at Market Open

Dynamically optimized environments present unique challenges for trading systems. Dynamic optimizations give us faster code, but can also bring temporary slowdowns, often at the worst possible times. After GC complaints, the most common issues we hear about in Java-based trading systems have to do with “warmup” behavior and de-optimization slowdowns. These seem to predictably hit just as the market opens, resulting in slow trades when speed matters most. In this talk, Gil Tene (CTO, Azul Systems) provides an overview of JIT compiler optimization techniques and their impact on common market-open slowdown scenarios. Gil also covers the technical issues behind such slowdowns, and discusses new techniques that may be used to avoid them, including the use of features specifically built to tame the JVM and improve behavior at market open.
