Context and Motivation The current article describes a series of Java Virtual Machine (JVM) Just In Time (JIT) Compilers micro-benchmarks and their results, relying on different optimization patterns or intrinsics support. For the current issue, I included two compilers from OpenJDK 64-Bit Server VM version 13 (build 13+33) C1/C2 JIT Graal JIT From my point of…
Context and Motivation The current article describes a series of Java Virtual Machine (JVM) Just In Time (JIT) Compilers benchmarks and their results, relying on different optimization patterns. For the current issue I included only two compilers: Oracle HotSpot C1/C2 JIT Oracle HotSpot Graal JIT In the future, I might extend it to Eclipse OpenJ9, Azul…
Motivation Current post tackles the problem of chaining (or linking) multiple lambda calls which seem to be differently optimized by the HotSpot Just In Time Compiler C2 (i.e. JIT C2) and GraalVM JIT Compiler. In this regard, I would propose to start detailing the problem, to run and check the benchmark results, to find…
