Explore the potential of Java on ARM processors in this 42-minute Devoxx conference talk. Delve into the theory, applications, and workloads of Java on ARM architecture, examining how ARM CPUs compete with x86 in cloud deployments. Learn about the Java ARM port features, performance of specific workloads, and recent changes in the Java ecosystem. Discover which metrics can be optimized using ARM servers and which workloads are best suited for this niche. Gain insights from Dmitry Chuyko, a performance engineer at BellSoft, as he shares his expertise on OpenJDK optimization for x86 and ARM, Java in containers, and the company's Liberica JDK distribution. Cover topics such as ARM chipsets, sensors, data gateways, ARM cores, OpenJDK, Java size, ARM processors, hardware threads, supercomputers, Docker, memory models, compilers, ARM instruction sets, performance comparisons, typical Java programs, micro benchmarks, and cloud instances.
