Understanding the JVM and Low Latency Applications

Explore the impact of automatic memory management and Just In Time (JIT) adaptive compilation on application latency in the Java Virtual Machine (JVM) through this comprehensive conference talk. Delve into performance considerations, heap layout, and garbage collection concepts while learning strategies to minimize latency effects. Gain insights into GC-friendly programming techniques, subtle object retention, and the Garbage First (G1) collector. Discover quick rules of thumb for optimizing JVM performance and understand the ideal garbage collection scenario for low-latency applications.
