JavaでCPUを使い倒す！ ～Java 9 以降の CPU 最適化を覗いてみる～（NTTデータ テクノロジーカンファレンス 2019 講演資料、2019/09/05）This document discusses optimizations for Java programs to better utilize CPUs, especially newer CPU instructions. It covers how Java code is compiled to bytecode then JIT compiled to machine code at runtime. Improvements in OpenJDK 9-11 are highlighted, including support for Intel AVX-512, fused multiply-add, SHA extensions, and reducing penalties when switching between instruction sets. Optimizi
