Garbage Collection Optimization for High-Throughput and Low-Latency Java Applications
Garbage Collection Optimization for High-Throughput and Low-Latency Java Applications High-performance applications form the backbone of the modern web. At LinkedIn, a number of internal high-throughput services cater to thousands of user requests per second. For optimal user experience, it is very important to serve these requests with low latency. For example, a product our members use regularly
Garbage First Garbage Collector (G1 GC) - Migration to, Expectations and Advanced Tuning
Since JDK 9, G1 GC is the default garbage collector (JEP 248). Up until 2017, Monica has shared some G1 GC details, performance tips, and optimizations that help G1's adaptiveness and provided advice on manual tuning. Since then, G1 has come a long way in improving its adaptiveness. In this session, Monica will cover most of the important optimizations that are delivered from JDK9+ and how they ca
Everything I Ever Learned About JVM Performance Tuning @Twitter
G1, CMS, Shenandoah, or Zing? Heap size at 8GB or 31GB? compressed pointers? Region size? What is the maximum break time? Throughput or Latency... What gain? MaxGCPauseMillis, G1HeapRegionSize, MaxTenuringThreshold, UnlockExperimentalVMOptions, ParallelGCThreads, InitiatingHeapOccupancyPercent, G1RSetUpdatingPauseTimePercent, which parameters have the most impact?
